I have experience with both:
Powertrax - this is in my truck. you can only use it if you have an open carrier installed (one wheel peel). If you can do a brake job you can install it yourself with no real differential experience and no special tools required. It's very strong and reliable, a friend ran one on his truck with a LQ9, cam, stall and N2O into the 12's many times with no issues. It's a locker, not a limited slip - not the most streetable, but you adjust to it. It is gear on gear. I park daily in a public parking garage, occasionally I'll hear it pop when making tight maneuvers, of course the parking garage amplifies all the sounds.
Eaton - I've ridden in a few trucks with the Eaton Posi. You'll need to know how to set up gears to properly install. They have a good reputation in the performance world. They engage and disengage very smoothly. It has clutches that will wear over time. More expensive than the Powertrax, especially if you have to pay someone to install it.
That's all I can think of off the top of my head. I picked the Powertrax because I could install it myself and the price was cheaper so that had me sold. At the time my main goal was to get traction while pulling boats out of the water, later a friend put one in his truck for a racing application and he was very satisfied with it.

I've had both as well (have an Eaton LSD right now). The Powertrax lasted about 3 years for me. I used it in my DailyDriver. It (suspiciously) gave up about the same time I put the LS1 in my truck. When it gave up, boy did it. I tore 3 teeth off the ring/pinion and shot at least one of them into the aftermarket differential cover and cracked it all the way through!! So, that was an easy $1200 down the toilet.
The Eaton, no problems, its quiet, it does engage, but I do notice a difference in the tread wear. The Eaton is rebuildable vs the Powertrax which would have to be bought and reinstalled. The Eaton is a heavy product by comparison, but I don't know that there is necessarily any performance difference - at first I thought there might have been.
