Basically, this is very similar to Starmie and Empoleon, except that it beats a larger number of leads at the expense of Stealth Rock / Rapid Spin.
Vaporeon can of course provide support to the team in ways that Starmie and Empoleon cannot. Wish and Heal Bell are notable options in this regard, since Vaporeon will certainly be returning later with its fantastic bulk. Starmie also performs badly against some leads like Jirachi, who U-turns out, Aerodactyl, who 2HKOes with Rock Slide or even EQ after LO recoil, and Tyranitar, who survives a LO Hydro Pump almost all of the time and OHKOes back with Payback/Crunch. Empoleon loses to Infernape and other fighting-type leads, as well as missing the OHKO on Tyranitar due to running Focus Sash/Chople berry, and losing to Mamoswine (increasingly uncommon but still.) Oh and Vaporeon is a massive surprise and an embarrassment to your opponent!
Golduck is faster, has Brick Break to stop screens, and can get KOs on everything Vaporeon can =P
Vaporeon's bulk is the main reason to use this set. It's an interesting lead which can provide a sturdy pokemon to use later on during the battle. If it were me, Wish would be a necessity.
