Dr. Rogers is pretty much world class though I don't really like the term "world class", different surgeons have slightly different offerings. Dr Rogers pioneered a lot of the techniques that other surgeons use and is always in communication with the other "elite" surgeons on ways they can all improve.
He won't do the mega density sessions that you'll get in some other clinics (by choice), but his work is superb. That being said, still do your research. I will *absolutely* recommend any one have a consult with Dr. Rogers though, his quality is at least as good as the very best in the world.
I've had two procedures with him, and will almost certainly get a third to finish the job. I went through all the "top" surgeons globally and still came back to Rogers as the best choice for me (though of course YMMV).
The deal breaker for me was he was the only surgeon amongst the worlds best who was able to do my hair transplant without shaving my head. He's also an extremely nice and genuine guy, you meet him at a consult rather than having to deal with some lackeys.
I've got loads of pictures and videos of the procedures in my progress thread here -

One thing I will add, the UK does have some *terrible* surgeons (much like any other country I expect), and you'll read a lot of comments from people who have had bad procedures who will then issue a blanket statement that *ALL* surgeons in a given country are bad because of it. Speaking as someone who could have gone to any clinic I wanted, and actually went to Dr. Rogers (twice), I like to think that adds a little more weight to my comments
