Do you plan to stay on Verizon? I would recommend you get the Nexus S. Pure google experience and latest updates with a super nice screen and speed phone overall makes me recommend it to everyone.
However, if must stay on Verizon, I would recommend the Bionic. That looks like it's going to be a killer android. Hate motoblur? Flash a custom rom.
I think making the statement "flash a custom rom" is not something that just be thrown around. You always have to account for users who may not be as comfortable as you wish rooting and flashing roms. Not knocking you, just making a statement.
The LPP is a good suggestion for replacing MotoBlur in the terms of a launcher but it doesn't remove every component of Motoblur. Much like Sense & TouchWiz there are apps & components of the OS that the company modifies to fit their skin. For example: HTC changed contacts, gallery, dialer, etc. While they aren't "Sense" they're still aspects of the underlying skin.
As someone else pointed out, using the LG Dare as your basis for a software keyboard is a poor one. You can't compare a dumbphone keyboard vs a smartphone keyboard. Completely different software, hardware, build, etc.
My recommendation: wait until at least the TBolt comes out and then go into a store and try them out. Narrow it down to which one (or two or three) feels good to you and then from there get people's experience. Ask about and read about the features that matter most to you, this way you don't find yourself becoming overwhelmed with the amount of information that is out there of what people hate & love about a phone.
