There really is no best race for any class. Beginning stats are different, certain races have higher INT (Erudite for one). But over time, that differentce will not matter as armor and weapons will overcome it.
Here's a list of racial starting stats.
My INT is 225 buffed, mainly due to armor and weapons. Click on my sig link to see what gear I have.
So it really comes down to what race do you WANT to play. Does a Ogre Summoner make your fancy? How about a pig-tailed wood elf? Troll?
Good luck and have fun with it!
