Well unlike c90 where you have to check out on arrival wall (something like 7 scopes plus 3pms) and either departures or satellites (another 6+ scopes) at sct you on get checked out on one area, and you stay there until you bid to go to a different one... And at that point its exactly like bidding for a different facility.
The lax area, which is the only thing I'm familiar with, isn't as complex as you'd think... Its simply volume... its way easier having to only deal with arrivals than it is at, say C90, where you have to learn about departure routings, vfr towers, vfr a/c, etc. So getting checked out here is quicker, but by no means easier, simply because you don't have to go through 10+ scopes.
