I've the LE37M86 (which I believe is essentially identical to the M87). It's a great set, with decent blacks and a very crisp image. The colours aren't quite perfect, but with a bit of tweaking it can look very good. I've not yet experienced any of the reported bugs (having owned the set for a month now), so perhaps many of them have ironed out at this stage. The internal sound isn't great, but that's to be expected really.
Watching both sets side by side, I found the LG to have weaker blacks and a generally 'weaker' image than the Samsung (of course calibration settings may be the cause here).
