Neither of those are bad choices for casual internet browsing. If you want to stream videos often, I would suggest trying to find something with a little more RAM... 4gb minimum, in my opinion. The storage space isn't all that important with streaming and browsing... that gives you some options to save some pictures or something like that... but the memory can net you noticeable improvements. The more the better when it comes to memory.

I've been working on and with computers for about 9 years for a large corporation. I don't claim to know it all... I know very little in the grand scheme of things, but that's my opinion.
