I think the only advantage would be cheaper housing. They are fairly typical suburbs so it all really depends on what kind of lifestyle you are looking for.

Traffic going North/South is getting really bad, so if you are wanting to be central/downtown during the weeknights you're going to want to stick around for a while and delay your commute or somehow offset your commute.

I have a coworker who lives in cedar park (our office is by UT) and fortunately for him his manager allows him to come in around 10 and leave at 4 to miss the traffic, but he has to make up for hours later in the evening.
