It depends on your commute route -- how hilly it is, the quality of pavement, whether there's any gravel or dirt. For my commute, I would take the Gatorskins hands down because they are lighter and roll faster than Paselas. However, my commute is very hilly with pretty decent pavement the entire way. I tried Paselas for a while and they felt slow, heavy and sluggish. I commute now mainly on Conti 4 Seasons and GP 4000s and rarely ever get flats with excellent tire wear.
