I have to agree on the Engadget review that a lot of features were not mentioned, but seriously CNET as reliable. Just one example, cnet says in the One X review that quad core is overkill in the negative section but then say how great it is on the s3 :/
I think GSMAreana seems the best so far
My point of bringing CNET review was for specific purpose of benchmark numbers. I don't consider CNET review as-a-whole over Engadget review or vice-versa.
GSMarena is usually very detailed, always a very safe bet in terms of quality.
I also prefer others like Anandtech, Nordichardware (their review of SGS3 is not up yet), swedroid etc.,
