Having used quite a lot of both they are great films I've had no quality issues with 120 or sheet film. It's hard to chosse which to use but I prefer the 200 for hand held work (in 1200 and am happy with the 100 for LF.

Yes they aren't box speed but then I never used Tmax 100 at box speed either it was best at 50EI, APX100 was true to its box speed though.
