The golden age of SF was apparently in the 1930's in the USA, when there were plenty of magazines and most of the now dead original SF writers learnt their trade. Much of what was written was pulp, but then I would say the same thing today. Plus gibson has been around for 20 years and so has Banks, the first "culture" short story is over 20 years old. New (As in first widely pubshed as far as I know in 2000 and since then as far as I know) SF writers in the UK just now include:
John Meaney
Robert Reed
John Morgan
Adam Roberts
Alastair Reynolds
I personally only really like Meaney and Roberts, if youve read any of the above I'm sure we can have a good discussion.
As for Ken Mcleod, hes not brand spqueaking new any more, I have 3 of his books 2nd hand in paperback, hes been getting published for over 6 years now, which to my mind makes him old hat. Certainly I havnt bothered reading his new books, it just looks boring.
Blueskelton, I think there have been people who have matched Heinlein and Dick in some ways, but then they were also fairly individual authors, so being better than them is hard. You would have to specify what was so good about them in order to compare and contrast with modern authors.
