The real main difference between Bewear and Furfrou is that Bewear hits a LOT harder and is more physically bulky due to much higher HP. I don't think anyone thinks Fluffy is better than Fur Coat. It's obvious Fur Coat is better.
Furfrou is, however, a competitively useless character.
After doing calculations, the only thing Furfrou can take better than Bewear are fire type moves and special moves, and even then, not that much better due to Bewear's much higher HP.
Furfrou and Bewear are both bulky pokemon with no good recovery options. The difference is that Bewear can actually threaten things while Furfrou has to rest stall.
- 1/16 of Furfrou's 354 max HP: 22 HP
- 1/16 of Bewear's 444 max HP: 27 HP
Where Toxapex is a Wall.
Bewear is a bulldozer.
Bewear's HP outweighs the difference in Special Defense so much that Furfrou can only take special hits only a couple of decimal places better than Bewear. And due to how Pokémon rounds decimals they will generally be taking the same amount of damage specially.
Furfrou only takes physical fire type moves about 5-ish percent better than Bewear usually. If the only thing Furfrou can take better physically is fire type moves, while Bewear takes EVERY other non-super effective type move MUCH better, and they take about the same from special moves, there's really no comparison on who has the better survivability.
Bewear hits like a bulldozer while Furfrou has no real strength when it comes to actual play. Bewear packs Hammer Arm, Superpower, Return, Ice Punch, Earthquake, Thunder Punch, Payback and more. Furfrou gets considerably less attacks to work with that are weaker and provide less coverage.
Bewear can beat:
and many other OU Steel and Rock types that think it may even have the possibility of staying in safely. Bewear also cannot get walled by stalling Pokémon like Toxapex and Celesteela because it packs Taunt. Furfrou cannot learn Taunt.
There is absolutely nothing superior about Furfrou to Bewear.
For every benefit that Fur Coat has over Fluffy, it is negated by Furfrou's terrible stats and terrible movepool. Bewear will always be selected more because it doesn't have the same weaknesses other Pokémon like Furfrou. Also, while I mentioned Toxapex this mon is not a synonym for Bewear, they are not interchangeable.
