Does magic trackpad 2 worth the upgrade from magic trackpad 1?

I have been using magic trackpad 1 w/ BetterTouchTool for a while now and came across a fair deal on magic trackpad 2.

My question is fairly simple that I did not find on the Internet / forum:

Aside from rechargable bettery, bigger surface area, haptic feedback etc...

What advantage will MT2 give me over the MT1 using BetterTouchTool?

Any feedback is much appreciated, but please focus on usability with BetterTouchTool.
