> 95 Speed just doesn't cut it for a sweeper unless you have Dragon Dance

> Tangrowth has significantly higher HP, so it can take hits better. It also helps that its Giga Drain is stronger, adding onto its bulk.

> Regenerator is THAT good because it can come in, tank hits, leave and then come in again ready to tank more hits. Leafeon's Abilities only help it in the sun, but it's outdone in that by things like Victreebel with a far stronger SolarBeam, Weather Ball and Sucker Punch.

> Swords Dance would be great on Leafeon if its coverage moves weren't so horrible. Mono Grass just doesn't cut it unless you have really good secondary STAB or just good coverage. Besides Leaf Blade, all Leafeon can rely on are Return, Knock Off and Iron Tail, Double-Edge, X-Scissor and Quick Attack. Meanwhile Tangrowth has access to Rock Slide and Earthquake (with Rock+Ground being 2nd best coverage combo in the game) as well as Knock Off in addition to Poison Jab, Brick Break and Rock Tomb. Because Tangrowth also has a Special Attack stat it can actually use, it makes use of moves like Focus Blast, Leaf Storm, Sludge Bomb and it can run Hidden Power Fire to kill Ferrothorn, Skarmory or Scizor and Hidden Power Ice to kill things like Gliscor.

> More people use Tangrowth because it has more to offer.
