Great tools for bug tracking, and then some

Hey guys, this definitely feels like a "just google it" question, but I didn't come across good discussion on this yet.

what do you use for issue tracking and metrics?

I've used clearcase extensively, and its WAY too detailed and complicated to use. its nice to have the features, but when you have to jump through a dozen dialogs and checkboxes just to send a bug to testing or change the status to 'in progress', its way too much work. ontime seems to be the same. you know what I mean. a tool that isn't easy to use isnt going to get used no matter how many features it has.

basecamp is pretty great, but its too highlevel. I cant see developers using it to worry about branches of code and releases and bugs.

so basically, I need a tool that is somewhere in between basecamp, msproject/clearcase/ontime, is properly usable for devs.

I know its out there.
