Well it's quite much a matter of opinion.
But I like firefox alot more.
To try it go to www.getfirefox.com
and download it.
And yes, if u try it and don't like it then u can just go to control panel and choose add/remove programs. And then just uninstall it from there.
But it takes such a little amount of space that it doesn't matter if u leave it on ur computer.
