That type of "top hosts" site usually has no real goal other than maximize income via affiliate commissions. The tops themselves are, at best, a personal opinion of the site's owner.
Are you not satisfied with Godaddy? What is it that bothers you most?
Fasthosts is owned by 1and1 (or its parent company, I don't really recall). In any case, there should be plenty of feedback on both (most I've read didn't seem so stellar). I don't seem to recall reading anything about Easyspace.com. They're probably very much UK focused. Is that what you're looking for, a UK based host?
I am considering upgrading to a Virtual Server.
Are you sure you need to do that? Your traffic levels don't seem to suggest that shared hosting isn't a feasible solution for you anymore.
