Sassie is a platform where each MSC has a job board. Presto is an aggregator in that it shows shops from Sassie MSCs all on one map. The problem with Presto is that A, not all MSCs use it, and B, it lags the job boards by several days. So for instance Intellishop might not use it at all and Bare might use it but by the time the good shops are on Presto they're already taken, or they're taken before they ever show up. Basically what shows up on Presto is the crap (IMO). I never use it and have never seen a shop there that I'm interested in even though I do a lot of work for Sassie companies.
