Relax, you left Windows and all it's viruses along with your Dell, in Mac land we do not have to worry about about such things. Just use whatever browser suites you best. Personally I use both for different things/sites.
I use Safari even though it probably isn't as good when compared to Camino. However, I'd rather sacrifice a couple microseconds now and get used to Safari, so when Apple gets it to version 1, I will be fully prepared to use it to its fullest. Not that it would be hard to learn how to use a new browser, but I'd be a little better equipped to do so.
I'd like to mimic everyone who says "whichever suits you," but I can't. CAMINOCAMINOCAMINO!
As for managing your links: Click the "Sidebar" button at the top right of your window. This will open a pane similar to other bookmark managers in rival browsers.
Use camino for now, its was more of a browser than safari is, its fast and its got alot more features but safari is comin back . If you can get your hands on Safari v71 , use that. but if not then use camino
