Nicole, don't worry about either area being "too touristy and crowded". ANYWHERE in Ireland can fit that description at times.
I was on a RS Tour last October, and Dingle was definitely one of the highlights for me. The music and general "ambience" of the town is great! I enjoyed the Ring of Kerry also, BTW.
One caveat though - be VERY careful driving in Ireland, as it can be hazardous both in terms of MVI's and "mechanical" problems. While there I spoke with one traveller that "hit something" and tore part of the front end out of his rental car. Another driver told me that a "curb jumped out at hit the car", which destroyed one of the tires resulting in "down time" of a day or so (weekend) to get repairs.
Be sure to have good Maps and/or a GPS unit. Some of the smaller roads are not well marked.
