Hehe, agreed. I wanted to switch A LOT of times, but always found myself sticking with my warp. Its specs are a little outdated (and I had to buy an extended battery), but with the high support from the dev community, we've managed to make it almost lag-free and definitely better than out of the box.
But if you REALLY want to upgrade, I think you should get the Warp Sequent (good dev community too) or the latest ZTE phone, the Boost Force (seems like it's definitely worth it for its price, with its dual core and LTE compatibility). It's been a while, but I read that the LG Venice has a locked bootloader, which makes it hard to run CWM. Also, if you force uninstall some stock apps, you'll brick the phone.
If you can spend a bit more for a phone, I'd definitely definitely get the HTC SV One. It has a MUCH better battery life compared to the ZTE Force (and I think the Galaxy S2) and it has a bigger screen (.3 inches). And it also has a dual core and is LTE compatible! I'm not sure how developed that community is though. I think they managed to root it, but it doesn't have CWM or any roms yet.
