Hi,
I have tried Alesis strike for a week, the playability on hihat is not on par on Roland either MIMIC, there is lacking on transition, extra tight hihat, transmunication and articulation, the depth of the sound is not on par from MIMIC, swell are not smooth, probably because of 200mb limitation and no real mic + GIGABYTES per kits like true VST have\MIMIC. The loading time, those affect the sound, from v1.3 and v1.4 I tried and it is evident, sample are not all loaded, some sound kick in late, and something even no sound, depend on firmware, I tested v1.3 and v1.4. There is the normal loading time as before, just different way.
I would take 2box before strike, but not change mimic to 2box, has more capability on triggers accuracy, no limit per kits, and editing that 2box can't have. I had the same conclusion as Jerry, which have drumit5, drumit3, but his main module is mimic, he use drumit3 as addons.
