As for build time I would say it can take closer to 5x as long for me anyway but that was with all the upgrades.
I built both about two months apart. Caveat: I built the S.E.X. from scratch with both C4S and impedance switch upgrades applied. This is NOT - I repeat, NOT - recommended, because you have to sort through several separate manuals and decide how to modify the stock build as you go.
I mainly did this because I got into trouble when upgrading the Crack with the Speedball, because I had built it too well. I barely had enough leads left to bend certain caps out of the way, and desoldering my super-crimped joints was a real pain! That said, in retrospect this is not at all required. Nothing needs to get bent out of the way to make room in the S.E.X., the upgrades are simple to install, and I strongly recommend building stock first so all of the pictorial instructions are correct.
I know, I know, "do as I say, not as I do..."
If I had to describe the build, I would say simply: The S.E.X. is just more Crack. It's more complex like a larger LEGO model is more complex: it just has more parts. Assuming you know how to put these parts together, it just takes longer. Use a decent iron, make sure you have rosin/flux core solder (Kester 44 is my standby), be patient, triple check your build is identical to the final picture(s), and it's definitely possible to build the S.E.X. first.
Caveats: Because you make more connections if your soldering technique isn't perfect there's a higher chance you might get a cold joint. Also, since there is more going on it's possible to miss something, and tracking down issues is a bit more complicated.
