pro parts vs fenderwell

Just a few questions. If you had a choice between pro parts semi fenderwell headers, and full fenderwell headers (both 2" tubes), what would you go with? if you run the p.p. headers, how tall of a tire can you run? is the trans easy to get out? ground clearance? I know with full fenderwells, you'll need a 165ish tire. thanks for the info gang!
