Generally speaking, any amp sounds better when "driven". This is especially true with tube amps, but also with solid state in that a speaker sounds better when it's pushed. So bigger is not always better. However, you will definitely have the power if you need it.

Make sure you try the amp at volumes you will actually be playing at. If it still sounds good to you, then that is what you should go for. As to exactly which amp, well, there will be a proponent for every one out there. Just depends on who you ask.

Good luck!
