Do you have any pictures which show the under wing, especially the underside of the primaries.  These are strikingly pale on 1st winter G-w Gull.  I would favour G-w Gull, but without better photos it is difficult to be sure.  I think the overall uniformity of the bird (especially the lack of a pale rump/uppertail coverts) fits G-w Gull better than Slaty-backed.
