I actually agree with Patrick. Neither Scrafty nor Suicune seem as good as they once were about a year ago. Dragon dance scrafty is near unviable becuase of all the scarfed fighting types and with offensive roserade now a thing, calm mind suicune has a harder time to sweep. BU scrafty has a lot of significant weaknesses too and gets destroyed by the very common heracross (it can zen headbutt but BU scrafty almost never runs this over rest plus it doesn't ko hera). On top of this scrafty really isn't that bulky in the first place, reaching only 334 HP max and can get pummeled on the special side by things like specs Kingdra and Togekiss even if it's boosted its defense.This isn't about CM wars, sorry if this comes off as a bit rude, but imo you're arguing for the sake of arguing. Uhm, CM wars imo is p rare in UU, CM slowbro being even rarer. Suicune's special bulk imo makes it a wayyy better sweeper, while also shrugging off status. A well played suicune doesn't need to have reliable recovery as long as you heal at the right time. Also it has massive physical defense so it can take psyshockes, but that's beside the point. Gligar imo is a TERRIBLE argument. It sucks in this meta, period. Also shed skin variants of scrafty outstall it. And imo these are easily top 5 setup sweepers.
tl;dr ilove scrafty and suicune
I love suicune too but it also faces competition from other setup sweepers like raikou and even though it has great defenses, its defensive typing is somewhat mediocre and only really helps against darm anymore (it no longer appreciates switching into victini). It too can get pummeled by sets that didn't really get used before like banded/swords dance heracross and LO roserade.
