[Verizon Droid Charge] distortedloop:
There's several threads along these lines that you should check out, so skim through the section and read them, even the one about "learning to hate the Charge" or something like that...you'll get plenty of pros and cons and TB vs Charge comments in those, but since I feel like whining about my Charge I'll jump in here. IF you don't read my whole post, at least check out the last paragraph, you might like the idea.

IF, and that's a big IF, the Galaxy S II ever comes to Verizon or ATT with an LTE radio, I'll be all over it once it's rootable, but since you're up against the expiring unlimited data offer, there's just the two to choose from (Charge, Thunderbolt).

I have both, and it's still a tough call for me on which I prefer. So many pluses, and so many minuses on both.

If I had to choose one right this minute to toss away, I think it would be the Charge, though. The Charge has got about the best damn display I've ever seen on a phone. iPhone 4 is sharper, but smaller, and the Charge blows away the iP4 in the contrast and inky blacks department.

The Charge is lighter than the TB, by a very noticeable amount. It's arguably got better battery life, but seriously, you won't be happy with it either. If you're in a spotty 3G area, the Charge seems to have exponentially better battery life than the TB, but in a solid 4G area, they both suck. I haven't spent enough time with both in a solid 3G area to compare yet.

The Charge's screen seems scratch proof without protection. Mine rides naked and has no mars. It fell out of my pocket on the leg press machine the other day and the front hit the metal bar on its way down. No damage to the screen but a small nick in the bezel (which is soft plastic). The Thunderbolt is a scratch magnet- treated mine with kid gloves, but no protection, and it's still somehow managed to get two nasty gouges in the screen.

The Sammies are pretty good at playing any media you throw at them, not so sure about the HTCs.

The Charge's hardware buttons at the bottom are pretty nice; I didn't think I'd like them, but once you get past the cheap plasticky feel, they're a solid competitor to the capacitive ones.

Those are about the only major plusses on the Charge for my usage.

Major minuses include a laggy as heck phone unless you do the voodoo ext4 conversion AND install the Gummy ROM. VooDoo alone, debloating, using different launchers, etc, did not fix the lag on the Charge for me. Gummy seems to have for the most part, but there's still an occasional sluggishness on waking the phone or switching some apps.

The plastic is cheap feeling compared to TB. It's a big issue for some.

There's no kickstand on the Charge. I know I'm not alone in thinking this is one of the coolest, most obvious enhancements to a phone to have. One of the big Android blogs, Android Central I think, made a blog post along those lines just recently.

There's no Gingerbread yet for the Charge, but there is (unofficially, anyways) for the TB.

You mentioned you hate Sense, but with the BAMF Sense 3 ROM I am in love with Sense. It's the slickest thing I've seen on a phone for a launcher and some cool widgets. I've been a CM7 and Launcher Pro guy for all my Androids since the N1 once CM7 became available, but for the TB, I think it will stay Sense on mine for quite a while.

We might see more activity with the Charge development-wise, it's still fairly new, but I believe that by the this time in the phone's life on the TB we had a lot more activity. We don't even have a full and proper ClockWork or Amon Ra recovery for the Charge yet. Imnuts has given us a pretty decent one, but you'll soft-brick (or worse) your Charge if you try to do a Nandroid restore with it, and unless I missed an update, you have to do a battery pull to reboot if you try a factory restore/wipe on it.

All that said, and my overall preference for the TB...why not grab a Charge and play with it for a while in daily use. GET IT AT COSTCO. You'll get locked in with the unlimited data plan, but unlike VZW purchased phones, you get 90 days to test drive the phone itself. 14-day right to cancel on cell plan still applies though. If you just hate the thing, you can go back and get the Thunderbolt, or better yet, by August or end of September when your 90 days is up we'll have some more choices (like maybe that oh-so-sweet Galaxy S II). ;)
