You want the SS, if you just want a rabbit moveset, theres plenty other SS out there. If you don't go first with a Rabbit in pvp, its dinner.
In my book, most pets, given multiple breed options. BB is the worst, followed by HS.
The DMF rabbit has SS, BB, HS breeds available only. A pure breed and the 2 worst. Easy choice.
One might think H/S is good too/speedy too. 322 speed, you're losing initiative to 325 pets.
