Safari 4 vs. Google Chrome vs. Mozilla Minefield: Which is the best?

I qualify best in terms of speed and stability. I'm on Mac so I've only messed with Safari 4 and Minefield. Safari is still a beta and minefield may even be pre-beta. Though I previously preferred Firefox 3 on my mac (it ran better on ESPN 360) I'm really liking Safari 4. Some of my friends have Chrome and they seem really similar. Apple boasts that Safari 4 is the "world's fastest browser" but I don't necesarily trust their claims.

I've read conflicting reports between either Chrome or Safari 4 as being the fastest. So, again I ask: which is best?

Are you guys using Safari 3 or 4? There's a big difference. Again I haven't tried Chrome yet but I've not had any issues with Safari 4 in terms of bugs, glitches, pages not loading correctly, or pop-ups.tazzydnc
