I got a Packard Bell, and I reckon they're pretty darn good actually, I wouldn't say there is a "best" all round, maybe one is better for a particular purpose, e.g. gaming. However i will tell you what not to go for, Acer are generally considered to be crap, I don't like Dell either, I know someone that spent £2000 on a Dell laptop and its rubbish... cant think of any others, hope that helps.
