ok, you named 3 cons, one of which isn't even correct.
the gun is great for spacing because of the bayonet, the final smash is by far the easiest to kill people with out of the space animals, and he's easiest to get the smash ball with btw, if you play with items. and he's not even close to being a fox clone.
play with fox, then play with wolf, if you can't tell the difference, you have an IQ of 60 or lower. seriously, none of the standard attacks are even close, and the special attacks are even more different.
To name some benefits of his, his reflector has invincibility, his side b can spike edgehogs, all his smashes are two hits, and his front smash comes out very fast with great range, he's got a good air game and a good ground game, his projectile is one of the best, he has epic taunts, he's got good weight, but because of his stance he's not very tall, and there's many more, which i'm not going to go into now.
