I think it depends - I've owned "steve.org.uk" since the nineties and I used to be the first result for searches for both "steve" and "steve kemp" in the UK.
Now I've relocated to Finland and I happened to do so just as steve.fi was expiring. So I've migrated to that domain as the lack of nested domain is easier to handle.
I'm still in the top five for "Steve Kemp", but personalized searches make it a little hard to tell. (My biggest problem is that there are a bunch of sites that link to the baseball player, who shares my name, including wikipedia etc. Hard to outrank that!)
