As a computer expert, I will give you a list of what I think
Internet Explorer = Avoid like the plague its too slow for modern surfing. Just because it is bundled with windows it is not that good.
Firefox = Yes its open source, its much better than IE you can add on a load of stuff which makes you do other things, but it can be a little complicated for novices if not understood properly, it can be fast, but my it eats memory(RAM) like a glutton and can seriously slow your browsing experience to a literal crawl, also Java seems to crash it allot, which is annoying. for security and privacy it is top notch though. If you have a mac you will find no problems using it also
Chrome = Its Google, apparently not "Evil", your favourite search engine who wants your data when you search now wants to integrate that functionality inside your browser. Furthermore the browser experience improves if you get a Google account as you can get integrated mail and free 5 GB cloud storage, but be warned Google wants to know everything about you, so they can improve your internet experience, so if you dont mind and you like looking at ads targeted at your favourite things based on your search history or default tracking of your cookies, then yeah. It is fast also.
Safari = If you like apple then this could be the browsing experience for you, Its really pretty and does a good job, fanbois ( i.e fans) would cry sacrilege for you not using it. It is pretty fast, it will mean you will need to learn how to "surf" the apple way. But its a nice experience
Opera = No I am not talking about well proportioned ladies wailing in a theatre. This browser is very nice, a interesting one, blindingly fast very easy to use and understandable also. just install and run. It is very geared towards the user and can be used by novices and expert "surfers".
So what would be my choice, well I am a bit of a firefox addict, I mainly use for work, because it is good in my line of work, because of the addons it uses.
But sometimes I always say to those who have windows do not use Internet explorer its a beastly program.
But if you want a uncomplicated experience without the complete info overload then Opera is your best bet.
