Most of my stuff (as I seem to say all the time) doesn't sound as polished as most of the users on here, but there have been a couple of projects where I liked the end result better than I expected upon first hearing the tracks. What I tend to say is my "best" work tends to be the stuff that comes out better than I expected, considering what we used.
The first one is a modern rock band who wanted a "live" sound for their whole album, so it was tracked with all the instruments in one room (the players, too) and then the vocalist was in a booth his signal was fed into the live tracking room via PA...He used an AT4040 IIRC, and they had it slamming the preamp (UA610), so it's a little choked at times (they wanted "grit")..But, I think we got a decently usable sound out of it. Can'[t say I dig the guitar tones on this, but I kinda like everything else.
Basically used some compression, quite a bit of high end shelf EQ around 2KHz and some de-essing. Also some reverb, and natural room ambience from a couple room mics that were placed in the tracking room.
EDIT
Also, there is obviously no auto tune or anything like that on this...The backup vocals was their bass player, and they are a little shaky, but it is what it is. I applaud them for wanting to try this "all natural" type of tracking/mixing.

The other was a "test" project I did for a band that was eventually turned down. I was bummed because at the time (2 years ago) I thought it was some of my best work (still do). I can't say I dig the vocalist much at all, but I think we got a good performance, decent clarity, but still had some grittiness...Vocals were tracked with an SM58 into a Focusrite Trackmaster Pro into a MOTU 828. I just didn't care for his delivery or lyrical style, but considering the signal chain, I was pretty happy.
It was compressed pretty hard going into the trackmaster (as it has compression controls on it), so what we tracked with couldn't be reversed. Little bit of High end shelf EQ again, slight reverb, more of a "live room" plate style verb to make it sound a little more immediate and present rather than smooth and "epic" for lack of a better word. I tend to use a vocal plate with a short decay on screaming vocals because I think it gives the music a more immediate and urgent feel. If I want a bit more "space" I usually will mix in tap delays.
