Firefox vs Camino

I use Firefox and Thunderbird on the PC, and plan to get my first Mac 
once Tiger comes out in a couple of weeks. Considering that both 
Firefox/Thunderbird is available for Mac I was simply going to switch to 
the Mac version of these apps for a simple/smooth transfer.

However.... I've changed my mind for email and plan to switch to Mail on 
the Mac instead of Thunderbird, mainly for the Mac look 'n' feel and the 
Spotlight search facility.

That got me thinking about using Camino instead of Firefox, to keep the 
Mac look 'n' feel across all apps. However I like Firefox so much that I 
think I'd only really switch over to Camino if the following features 
are added.

1. Add Spotlight to Camino. Eg so bookmark names and cached webpages 
show up in a Spotlight search.

2. Add support for .Mac sync, same as for Safari.

Can't think of any other Mac-specific incentives that would tempt me 
over the platform independent Firefox but there's probably others.

I'd be interested in hearing other people's opinions about how Camino 
and Firefox compare (and Thunderbird and Mail for that matter)...
