what internet browser should i use?

Knowing that this will be an ongoing thing for me, i dare blog about the challenges that I'm experiencing specifically about the browser/s that i currently use.

Microsoft Internet Explorer 7: had to uninstall it since it was eating up too much memory and made other apps hang
Microsoft Internet Explorer 6: this i'm keeping as a back-up browser but don't really use it for lack of features
Maxthon 2.0: used to use this together with IE6 for the tab-console, but when IE was having problems, it too was bogged down
Mozilla FireFox 3.0: it just consistently crashes every few hours; also has this delayed 'space bar' when using chikka
Opera 9.5: this is what i was tinkering with after the FF 3.0 crash party, but it too had its own pattern of stops after a few days of problem-free use; and it so sluggishly loads chikka.com for the particular reason that escapes me.. and it's supposed to be the 'standards' based browser. so who to blame right?

So as of the moment, i'm using Flock (FF 2 based) and so far so good for now. And so I see that Mozilla has released a Firefox 3.0.1, maybe I'll try that one for size, just maybe.
