Off the top of my head SQ and CX are the only carriers with the 275,000kgs version that I know of, however I'm not 100% sure about CX.
LH, OS, VS and China Eastern fly the 271ton version (some also fly the 257ton version - 300).
I don't think there is any difference in terms of fuel capacity or engines - I know on the SQ343s, a 5% thrust bump is available for takeoff (for about 5mins). Basically you can carry more on the 275ton version before you start eating into fuel capacity.

I don't believe this is correct. The reason Airbus bumped up the MTOW from 271t to 275t was because Airbus wasn't able to meet its guaranteed range for SQ. As a result, they had to add additional fuel capacity and increase the MTOW.
