Hi,
I believe you have to try yourself because they are really wonderful instruments and you have to decide what's the detail that will decide the competition.
Just a small addition to the sampling section: T2 has up to 1G (even if I've no idea about loading times of such huge memory) but the small 32 Mb of Pa1X are compatible with Akai programs that you can find very easily and for cheap price now.
Don't know if this is important for you, anyway did a great job for me: I found different old but good Akai libraries (Miroslav Vitous is just one example) for very cheap price or second hand and this helped a lot with some sounds I was missing (piano, strings, drums).
Hope this help.
Regards
