My Top 5 currently:
RKO(can hit it on someone out of nowhere, just looks awesome)
GTS(looks absolutely brutal)
Swanton Bomb(when done by Jeff Hardy, it's such a great move, anyone else....meh)
Backcracker(Again, just looks brutal, and can be done anywhere)
Tombstone(Just for the legacy behind it)
Worst 5:
Pedigree(used to be a favourite of mine, but now HHH releases out of it halfway through and it looks weak, easy to reverse too)
Running Bulldog(ugh, just give Cody the Bionic Elbow)
Playmaker(takes so long to set up it can't be a winning move, can't see MVP winning a World Title with it)
Curb Stomp(So dangerous and difficult to execute)
619(the fact that Rey has to do a move after it tells you how weak it is)
I'm sure there's plenty more but that's all that comes off the top of my head
