Good Home Base for BO when you want to hike the "greatest hits" of the area.

Hello all! I know there are hundreds of posts on this topic (& I've read most of them :), but is Wengen a better home base for a first timer like me? Husband and I will be in BO for 4 nights in mid-September and my focus is hiking. I am a moderate to challenging hiker and he is easy to moderate (we've both done big hikes at Glacier Nat'l Park and Yosemite). Since it is our 1st time and not sure when we'll be back, I want to do: Schynige Platte panorama trail; Grindlewald First to to Bachalpsee; Mannlichen to KS; maybe part of Eiger Trial; Northface Trail; Murren to Gimmedwald; and the valley floor to Trummelbach Falls. Here is my issue, my first choice would be Murren b'c I love the more "in your face" mountain views of Murren, BUT I'm concerned w/time up and down the mountain especially if I am chasing good weather and b'c lots of stuff I want in on the Wengen side. Second, I'm concerned about the amount of sunlight in Murren in September and what time the sun dips behind the mountains, is it much earlier than in Wengen? Ultimately, I think I will be happy w/Wengen and it will give me an excuse to come back someday to stay in Murren! Thank you for any thoughts! (PS, I think I've settled on a 4 day Jungfrau Pass as we won't be moving beyond the BO bubble and we are not doing Jungfraujoch or top of Schilthorn).
