Iksar is always a better choice for a monk if your goal is the best possible monk at 60. If your goal is to simply enjoy the monk class and get to 60 with any kind of speed, human monk is fine. Humans have innately faster fists by a tiny fraction - it's such a small thing I ignore it, and it doesn't affect epic'd monks. And there will be a lot of epic monks given how easy their epic is...

You'll miss a bit of AC and a lot of regen difference in your late 50s, but you'll be sexier - if you care that much about graphic models designed in the late 90s. But suffice it to say the regen/ac bonus don't mean much until 50+ (because the regen difference doesn't start to really take off until then).
