I ran both on my old XJ, i prefered the 10.5's... i think you'll be happy with them. What backspacing are you planning to run?
When I still had my XJ I ran 33X10.5 r 15 BFG ATs with 4.5" of back spacing. The XJ had 5" of lift and 4.56 gears, so I had enough room in the wheel wells and enough grunt to turn them. I loved them. I would also not under estimate the need for a good side wall. In the 15" rim they are C rated. I could run my tires down to 7-8 lbs and not worry. I slit a side wall, but did not hurt the under layer and ran it 40,000 miles without any problem. BFGs are worth the price, I won't run anything else.
I had 255/85-16 BFG KM2s on my JK for 10,000 miles but they slid like crazy on rain-wet pavement. BFG pro-rated a return and I mounted 285/75-16 Cooper Discoverer STTs and was much happier.
I have 295/70-17 on my truck right now; same Cooper STTs, same degree of satisfaction.
