This is quite a collection. I just did a short comparison of various MuseSound perc. instruments vs. the CinePerc samples. On the whole I prefer the CinePerc sounds.
The Snare drum is way more defined than the free MS snare. The Bass Drum is huge (maybe a bit too huge...you may have to eq it in your mix). The triangle sounds great, with great clarity even on a quick 32nd note roll, which does not sound great with MS. Overall, a good library, IMO.
