Wow, what a ton of answers about Palau and the regions out here. (I live on Guam). Over the years as a former large dive shop owner I've taken groups to many of the destinations mentioned.
I've put together some (what I hope is unbiased) info on some of the areas on the link below. The one thing that I'd very strongly recommend if you are going to Palau is NOT go during late November thru April. It's really VERY busy there, all the rates go up, and it's not inconceivable to see up to 25-30 boats at the Blue Corner and some of the other sites. I still send lots of divers there but not during that season.
Here's the link. I hope this helps. While you're there take a look at the other pages. Gotta get a plug in.
