ubuntu , it's alot easier to use for me.. I don't like having to use terminal but in all honesty unbuntu seems to have me in it's good books..
I edited my post because you have a very good point .. so I'm sorry to come and say windows.. but personally I don't hate linux, infact I think it can do more then windows when it comes to command lines..
Mostly when I can't use my laptop because of some error or windows won't install I'd turn to ubuntu, it installs and works threw bad harddrives unlike windows.. I had a faulty harddrive at the time and xp wouldn't load because it had bad sectors, unbuntu on the other hand worked but still had errors about harddrive but I was pleased unbuntu could fly threw the errors
