Its totally up to preference. I'd suggest you just go with want fits you best. But to answer your question, in my opinion, I think Safari is best for my needs. Before I switched to a Mac, I used Firefox on Windows. It was my favorite browser by far..so when I switched over to a Mac, I naturally downloaded Firefox for my Mac. The main thing I didn't like about Firefox on the Mac within a year of using it was that it seemed bloated and it honestly looked ugly. To me it seemed like Safari loaded stuff a tad bit quicker. On the flip side, Firefox rarely crashed for me. Safari on the other hand crashes all the time. I also seem to have a lot of issues with flash when using safari. But the crashing isn't as bad as before, so I'll manage. Chrome is pretty good so I hear, but I'm not a huge fan of google. I love their search engine, but I hate how they have a finger in everything. Now since I'm not and at home with Safari, I'm too lazy to try anything else. As for right now though, I use Safari as my main browser. If I'm doing anything that is important, I usually open up Firefox too just to be safe.
