I got some Butron Plates. Works well when you need it. Board feels narrower, reacts a bit faster and you boot out less then without em. I tried it with hardboots too, pretty much the same, except that I don't really need it for hardboots.
I cannot comment on other plates, I'd say Gecko seems to be the best one. Burtons that I have are pretty average, I'm quite surprised I haven't broke em yet. It would be almost impossible to find Palmer PLS plates.
