Alakazam: As fast as you can. Learns all the same moves, but Alakazam can learn also Hyper Beam (which sucks)
Haunter: As fast as possible. Gengar learns a lot more with TMs and they learn the same moves at the same level.
Growlithe: 49, so he learns both Flamethrower and Extremespeed. If you afford a Flamethrower from Game Corner and want to buy it for him, 25. If you want also Flame Wheel even though he gets Flamethrower, 31.
