Anyone here tried SeaMonkey? Have any ideas and opinions about it as default browser and email client?

I want to try SeaMonkey.

I have 14 email addresses and though I access most in Thunderbird, I still want to keep some accessed at webmail.
This seems the way, one app for all, the ones in an email
client and ones webmail. I dont know anything about SeaMonkey, except what I've read.

Whaddya think?
