I liked LP (didn't try +), but because it has been abandoned, I stuck to ADW for a while. To me, ADW and LP were pretty comparable, but I liked some of the themes on ADW. I also tried Go Launcher Ex, but I was not a fan. It looked great, but it was (a little) laggy and ran my battery down about 5x faster than stock. ADW lagged less (still experienced some mild lag, a few FCs, and random restarting of the launcher), and I got the same or a tad bit better battery life than with stock. Well, I say stock, but I'm running Tweaked 2.0, so I really mean that.
I've been on Zeam for the past couple of days, and so far I like it. It doesn't have the themes that the others have, but the default skin is fine with me. Most of the themes I was using on ADW/Go were just variations of the default Zeam look anyway. I'm going to stick with Zeam for now because I have yet to experience any lag, and my battery has drained 8% in 3 1/2 hours with mild/moderate use. This is possibly the best battery life I can recall since purchasing my phone. Also, I mainly use the launcher to customize the dock (5 icons), hide the icon text, and resize the columns and rows, which I can still do on Zeam.
