I like the fact that it can be had for 200$ and it's one of those air/spring combo shocks. The adjustability is great because it's done through adjusting air pressure, and it's quite plush and smooth partially because of the spring half of the shock. Trail performance is noticeably good. And haven't had any problems with leaks yet, even when riding in cooold weather.
For the price difference between the air version of the Tora and the MX Comp ETA, I'd choose the MX Comp ETA.
