I agree the crit chance is essential, but there are other and better sources for it. The issue with attack speed is a) you get a lot from ambush (and also plenty from black cleaver and/or cloak and dagger) and b) it doesn't increase damage from your ultimate at all, and dishing out as much damage as possible during your ultimate is your primary job.

In my experience twitch's bread and butter early is expunge, but his bread and butter late is spray and pray. He can largely ignore the other at that stage of the game where he can pull off little more than spray and pray (and really doesn't need to pull off anything more if he does it right and focuses on AD). Attack speed can therefore make for a better early game, but it becomes useless late, and a lot of the gold spent on a phantom dancer is spent on attack speed, for an item that has no other utility (as does black cleaver). There are just much better items for it. Also, crit chance from IE and exec's calling or whatever else you get should be plenty; the more crit you get the less you essentially get from it.
