I2C - 3.3 or 5V?

For using I2C devices with Arduino, would I want to get the 3.3V or 5V versions?

If they're digital, is there any difference besides slightly lower current requirements with the low-voltage version? Does either have some advantage?

I prefer 5V parts if available just to not have to deal with 5V to 3.3V converters and having to find a 3.3V current source.
The link you provided is 5V compatible.

If I was running on a 3.3V/8MHz Promini, then I'd look for 3.3V parts.

Its all relative.
