Awesome Pokemon that suck

Are we talking suck suck, or tourneyf'ag suck.

Because I just know that the tourneyf'ags will pour in here and say something like "Hurp durp all Pokemon that aren't Scizor, Metagross, or Vaporeon suck."

Serious response:

You decide. If you use the Pokemon and it gets knocked out before you can really enjoy having it out, it's up to you to decide of it sucks or not. Xatu was never really useful to me, but it's a pretty cool Pokemon. In Gen IV it does have Heat wave + Psychic + Signal beam to work with, but that's pretty much one of the best offensive movesets it can really have. It's very limited in its use, and will usually go down in one or two turns. Luckily it has pretty nice speed, otherwise it'd get wrecked by anything of equal or greater level to it.

In the single player game I keep it around and occasionally send it out if I know it can beat whatever I'm sending it on. In an actual battle (doesn't have to be competitive battle, a tough in game battle is enough) then I'd save it for when I'm desperate, because it'd get taken out fast.

Overall, Xatu seemed like a Pokemon that could have been made better than it was. You'd expect it to at least have a pretty nice ability, given that it can see the future, or a wider variety of moves at its disposal. Xatu doesn't have much to work with, really.
