Biped Vs Cat Rig

It's getting close to final piece hand in time now, so the heat is on to get this done!
For my final video sections, I did tests to see what model I would use, CAT or Biped?
Here are two tests!

This is the Biped test. It is unfinished as I realized two things. One, the animation was running at 30FPS and the images used were exported at 24FPS. Animating with the Biped rigs are a bit tricky in some respects, features on them are smaller, like the hands (Where as the CAT rigs have larger squares), which made some of the animation tweak out and flip around slightly.

The CAT rig test for reloading. This is just a quick bash at using the CAT rig. For the final animations, it shall be smoother and feature secondary actions and what not. The image you see in the background was made using Tabletop terrain I use for Necromunda (Games Workshop). If you would like it, www.worldworksgames.com allows you to buy the .pdf and you mount it yourself. This particular one is Outpost 105, with Abandonned Building in the back, on the left. 

Like above, I used images rendered from a video at 24FPS, but had 3Ds running at 24, also. Like I said, things will be altered in the final piece, secondary animation, and possibly a prop of a weapon and magazine (as this clip shows reloading).

From these tests, I found that CAT rigs are easier to work with, and I shall be using these for my final piece.
