Best Split Screen Plugin?

I am using a lot of split screen effects for my guitar tutorials. In order to expedite the process I've been checking out a couple of split screen plugins--particularly the following by FxFactory and FCPeffects. Does anyone have any experience with these or have any recommendations? It seems that the FxFactory plugin can actually do more, however the FCPeffects plugin seems more user-friendly. Any recommendations are highly appreciated!
Thanks!

FCPeffects:

I am a big fan of all things FCPeffects. Simple and bulletproof. The price is a no brainer (always on the site). You will not be disappointed. I also use Tokyo Split Animator for fxfactory:

More money, but a deeper animator. For the price (with discount) you should just jump in with FCPeffects and enjoy it.

Check out the Tokyo/Hawaiki products on FXFactory. I use Hawaiki AutoSplit all the time.

Is there any split screen plug-ins that work with multicam clips?
Let's say I put it over a multicam clips and then I can choose wich angles are shown in the various screens?
