TH2 (full version) users: Upgrade worth it?

When I launch TH2 SONAR edition, I notice that all the amp models except two live inside a common "cassette" skin. I find that the two others (the THD and the Randall) are in a different league than the cassette ones (like much more attention was paid when modelling them). 

So what I'm asking the full version users is: 

1. The additional full-version amp models, do they have their own skins? 

2. Are they cool? Which are your favorites?

3. I already have a maxed out PodFarm outfit so I have more stomp boxes than I'll ever use. Problem is that most of them are crap. Are the 70 stomp boxes inside TH2 Full of better quality? Are they like Mokafix good?

There is a demo of the full product. Why not check it out for yourself?

Here is one of longer threads about the full th2 http://forum.cakewalk.com/fb.ashx?m=2655913

I upgraded to the full version a couple of weeks back. It took a couple of days before I got the serial number.
I also have POD Farm 2, Git Rig 5, Amplitube Fender but I just find the sound of TH2 has more weight behind it, less top fizz. But I have also played qwith combinations of POD amps into TH2 cabs, and to my ears the sound is better than just using POD Farm. There are a lot of amp models and FX in the other amp sims so they'll never be redundant.

For those who have upgraded:

-What efx can make use of tempo-based "BPM" features?
-Phasors: do they offer a sigificant variety of types?
-Choruses: do they offer a sigificant variety of types?
