what's the best UV filter for Canon EF 24-70mm f/2.8L II lens?

Your lens is coated with UV layer. I have B&W Clear Filter on my lenses:

I use the B+W XS-Pro Nano filters, have them on all my lenses.

Practically speaking, for a dSLR there is no difference between a UV filter and a clear filter - my advice is to get whichever one is cheaper. That does vary based on size, vendor, and geography. For example, here are some prices from Amazon.com today:

• B+W 77mm XS-Pro MRC Nano Clear 007M - $115
• B+W 77mm XS-Pro MRC Nano UV 010M - $73
• B+W 82mm XS-Pro MRC Nano Clear 010M - $126
• B+W 82mm XS-Pro MRC Nano UV 010M - $253

So, if I wanted to purchase from Amazon.com, for a 24-70mm MkI which takes 77mm filters, I'd get the UV filter and save $42, and for a 24-70 MkII which takes 82mm filters, I'd get the Clear filter and save $127.
