I'm in the same boat as you however I just renewed my NE2 a few months ago
I think it all will come down to your personal preference. Right now I'm deciding to go with VZW's TP because of the larger keyboard and design (I actually like the VZW design better than the Sprint version). I've also decided to go this route because I won't have to fiddle around too much to get the device to work the way I want - going through the long process to make the Sprint one work on VZW's network would save me some money but I'd rather have a product that VZW will support fully (so I can possibly return it if need be or get a replacement).
I can deal with the crippled RAM through tweaks and the locked GPS I'm just hoping will get unlocked in the near future (not an immediate need for me either, just something nice to have). I might even disabled TF3D all together and use my own today screen applications that are more efficient for using it as a PDA
