Verizon Phones Similar to Tmobile Sidekicks

Because I am so ridiculously fed up with t-mobile's service and would like to switch back to Verizon, I was wondering which phone is the closest to the sidekick?
I know the enV has basically been dubbed the "fake kick" but I'm a little confused about their AIM service.
I'd like a phone that has similar data services as the sidekick, and I was thinking between the enV or the Motorola Q but I am just a tad confused.
any help you can provide would be much appreciated.

The Q will require to get the Unlimited Data package which is $44.99 per month on top of your voice time minute plan. The Q is a smart phone, basically a PDA. The Envy is just a phone, just like the Sidekick. The Envy has everything the Sidekick has except the Envy has a better camera on it. It's a 2.0 mega pixel camera vs. a 1.3 mega pixel camera which is what the sidekick uses. The Envy is a great phone, you'll love it.

Envy man. Check em out, I had one before I was in my car accident and they're sweet.

thanks!
how's the aim service with on the ENvs compared to the aim service on the sidekicks? and the internet.

To be honest with ya, I like it better. Internet is sweet, but so is AIM.
