Gator is pretty nice but I find that I can do most of the same things with a Pig - not a lot of difference really, and if you need something longer then a fairway or powered-down driver will work. SM Roc is pretty overstable, too, but it'll turn if you want it to, whereas the gator will fight hard.
I didn't like the feel of the Drone in my hand, but I do really like the Sentinel and it's crazy overstable with some glide to it. The Trident is similar with a lot less glide if you're using it to fight strong winds. Both of these are very flat and the rims feel great. I got rid of mine and mostly use the Pig now, although I'll carry the Gator at times.
