With the lack of technical information on Airbus' website, I can not find the answer to the following:

Which engine on the A330 is a better choice in terms of cost, maintenance, emissions, fuel consumption, ect.?

If there were a single right answer for this question, there would only be one engine offered. Competition is very beneficial for the acquiring airline.

I know that the most powerful engine offered is the Rolls-Royce Trent 772 (72,000 lbs. of thrust); I also believe that its the market leader for the A330, followed by the PW4064/4068 and the GE CF6-80E2. Knowing Rolls-Royce's reliability reputation with the RB211, the Trent probably is the most reliable but also is likely rather costly to maintain given its three-spool design. This also means that it probably has worse fuel consumption than the PW & GE due to the fact that the RR 3-spool engines such as the Trent are heavier. The PW probably has the worst emissions - I've seen photos with exhaust trails coming out the back of PW4000's (not only the A330 but also the 777, 744, 767, etc.) that made them look like they were JT8D-powered. twocents

followed by ... the GE CF6-80E2

Correction: CF6-80E1

Correction: According to the AvWeek annual Source Book, the CF6-80E1A3 is tops with 72,000 pounds thrust, beating the highest thrust Trent variant, the 772B, which only offers 71,100 pounds.

Possibly. For the T-700 and the equivalent P&W and GE engines on the A330, the RR may be the heaviest, but on the 777, the T-800 is easily the lightest of the three engine options.
