Late reply, but a benefit to Gatr is a few things:
1. If he's catchered, he has a bit more survivability than Floatzels do.
2. He's not limited to a single energy drop, but as many as you'd like. A single interviewers question can theoretically bring up 8 water energies, assuming you had 2 Floatzels down, it would take 4 turns to drop, Gatr does it in 1.
3. If you for whatever unfortunate reason can't get Magnezone set up quickly, Gatr is more than capable of dealing 100 damage a shot.
Floatzel is certainly faster, but Gatr is stronger/heavier.
