I'm liking Latias so far. It also helps against Omastar (if I don't let it get a Shell Smash that is) who is also giving me problems. While I enjoyed Palkia's Speed a lot, taking 35% from Specs Kyogre's Water Spout is actually really nice.

Gliscor's set is non-negotiable. In my opinion, there is no room for anything else besides those 4 moves on its set. That is Gliscor's singular, bona-fide Ubers set, and while being able to prevent hazards would be awesome, reducing its effectiveness versus the other 99% of the Ubers metagame might as well make Gliscor an empty slot in terms of usefulness.
