EXS 24 Logic Sampler Users Group

I'm wondering if any1 out there has experience using the EXS24 & MOTU's Mach 5. 

If I'd appreciate your opinion on the following: 

1) what "BIG" advantage(s) does that the Mach 5 have over the EXS24? 

2) what DISadvantage(s) does that the Mach 5 has compared to EXS24? 

3) does is the Mach 5 run "VERY" stable on LAMP 6.3.3 or Logic Pro? 

4) side-by-side is the EXS24 as rich, advanced annd deep as the Mach 5? 

5) which has a more user-friendly interface? 

6) is the Mach 5 as easy to learn & operate as the EXS24? 

Thanks for every1s input and advise who responds,
