Nurnberg or Strasbourg... Which would you pick?

It would be helpful to know which other towns you plan to visit, but without further info, I like the variety that Strasbourg will add to a Germany trip.
If you are driving a German car, there are some traffic restrictions in the Strasbourg area requiring an emissions sticker. If you are just planning a day trip, you might have to park in Kehl and take the tram from there.

Both are nice, but I enjoyed Strasbourg more.

Aha... thank you, Balso.
That is an important piece of information that I had not considered.
Lodging in Kehl may be a workable solution that I will look into if we go this route.

I am curious, how broad are these restrictions?

We are traveling to a small town near Saarbrucken for a family history reason, and I thought it would it be possible to pass through Strasbourg and "cut the corner" of France in that area. I didn't think about two EU countries having conflicting emissions regulations.

Do you know if there are any restrictions on passing THROUGH Strasbourg, as opposed to driving around in the central city area?
(If you don't know, I will try to let google inform me, but personal knowledge is usually preferable for my starting point.)

Thanks again!

We have been to both numerous times and love them both. But if forced to choose, we both would choose Nurnberg. We have visited most of the historical sights in Nurnberg, but besides the sights we love the feel of the city. It feels less like a city and more like a town. The old part of town is just so comfortable. Good luck on your travels. I'm sure you will enjoy either city.

I've been to both and if I had my druthers, would go with Strasbourg. I think the city itself is more beautiful than Nuremberg, and has a lot more interesting things to see. The cathedral, for one, is magnificent and well worth a visit for its beautiy, but the city itself has a lot of culture and yet has a quirky side to it. There are many of the German-style half-timbered houses there, lots of wonderful restaurants and shopping, and some great museums if you like that sort of thing. I really enjoyed the Alsatian Folk Museum as well as the Musée de l’Œuvre Notre-Dame (Museum of the Work of Notre Dame). This museum contains many original statues from the cathedral but also many other beautiful works of art.

I really loved my visit here and would definitely go back, whereas I do not feel that same need to go back to Nuremberg. If you want, I keep an online journal of my travels and wrote one last year when I went to Germany and Strasbourg. You are welcoem to look at the photos and entries if you like. Here is the Strasbourg page: https://mostlytraveled.wordpress.com/2022/05/07/day-13-a-saturday-in-strasbourg/

We are WW2 buffs, so we would probably go with Nurnberg. Plus, the food and beer are really good. After visiting Normandy on a previous trip, it was meaningful to visit the Palace of Justice and see Courtroom 6.

BUT, Strasbourg has a lot going for it too. Alsace is a very unique part of France, and it does kind of feel like a French-German hybrid, and the Alsatian cuisine almost as good as Franconian/Bavarian.

I would like to visit Nurnberg for all of the historical significance
it holds... the nazi rally grounds, the courtroom for the war crimes
trials, the older history wrapped up in the town's central section.
However, my daughter and son-in-law may be less enamored of such
things than I am.

Outwardly, you're asking which city the forum members like better. Yet the preferences of your daughter and her husband seem to matter as well. So I'm left wondering what sorts of things they would appreciate. Any ideas for us to think about?

Nuremberg typically gets painted with the usual broad, Nazi-brush in guidebooks like Rick's. But there's more to the place than that. What about the museum of Industrial culture? Nuremberg is the home of the Deutsche Bahn Railway Museum as well. I'm guessing that "the kids" don't have a genuine castle in their hometown. What about medieval dungeons? I believe tours of those are ongoing. Nuremberg has some outstanding pubs. Then there's the Handwerkerhof, or Craftsman's Courtyard, with lots of little shops and food spots.

I've spent only two days in Strasbourg, separated by about 20 years. I don't like it nearly as much as Nuremberg, which I've been back to several times. Really like the vibe in Nuremberg. As for Strasbourg... Just a little "meh" for me.

We used a P&R (2015?). No more, no passing through without a badge. There you go:

Nürnberg and no intentional Nazi anything (site visits). Just enjoy the city. Fürth and up to Erlangen too. I think the foods better too.

I frequently pass by Strasbourg, I've only visited once.

I frequently visit Bavaria, and when I do it often has most of the time in the northern part of Bavaria, where Nuremberg is. We stay with our car from home just south of the city and take fast and frequent and cheap trains in. Not only Nuremberg but all the lovely places nearby.

So I vote Nuremberg.

If you have a non-German registered car you need a green Umweltplakette sticker for being near the centres of many German cities and many towns. It goes on the windscreen. German rentals come with it.

If you have a non-French registered car you need a yellow Crit-Air sticker for being near or even reasonably near the centre of many French cities and towns. It goes on the windscreen. French rentals some with it.

I have both an green Umweltplakette and a yellow Crit-Air stick on the windscreen of my car and registration in Belgium for their cities.

It isn't quite so simple as it was.
