You also need to remember that Latias usually runs enough Speed to outrun non Choice Scarf Palkia, so that means that Garchomp not only will KO Latias, but also not scarf Palkia. Further things is that with SR Dragon Claw will deal 359 Atk vs 236 Def & 321 HP (80 Base Power): 264 - 312 (82.24% - 97.20%) this means that Garchomp has a 58% chance to KO with Dragon Claw. If you can happen to make Palkia have to switch out more than once, or you have a layer of Spikes down as well Garchomp will OHKO with Dragon Claw.
This isn't to say that they are totally equal. Garchomp is by far the better revenge killer when it comes to ubers, but when it comes to sweeping while carrying a choice scarf than Palkia has a better chance. Without a Choice Scarf Garchomp has an easier time sweeping with Swords Dance and his base Speed, while Palkia tends to be a wall breaker.
Eh, agreed. Like I said, I don't look at ScarfChomp as a sweeper but a revenger or a finisher in the end to mop the floor. It does have a problem with the stall though (private said it before this post) but other than that ScarfChomp is an incredibly revenge killer. I do love the SDHabanChomp (in UBERS) but I do find it hard to setup and sweep with all the scarfers running around. On the side note, if it were ever to go to OU (I wonder how it will fare in HGSS meta hmmmmm)... Anyways yeah
