I've pretty much completely transitioned to SeaMonkey. The addons I use are: Adblock Plus, Flashgot and Seatabx (had to get this from a russian site, I can give you the link if you need it).
There isn't a Speed Dial extension that I found, but I never really used it much in Opera. To replace the functionality I needed for this, I just used the Bookmarks Toolbar (in fact, to create space, I dragged it up beside the top menu (where file, edit, view etc is). Of course this only works well if you have less than a dozen or so sites. There are SeaMonkey Speed Dial extensions called Speed Dial WebPage and Speed Dial, but they have not been updated for use in the latest version. I guess you can give it a try to see if it works.
I don't think you can get tab stacking functionality on SeaMonkey. You could try this addon: Tab Stacking
Obviously, depending on the functions you need, some of the other options mentioned here might be better. Firefox has more addons, so I can see Firefox or Waterfox with the Simple Mail extension more appealing depending on your needs. I haven't tried Simple Mail myself, but the email functionality of SeaMonkey is great. It seems just as robust as Thunderbird.
On a bit of a side note, I was tinkering around with Numion Stopwatch and SeaMonkey seems to be really quick in loading pages. In fact, Firefox, Seamonkey and Chrome seem to be mostly be about the same speed (within 1 second of each other), with Opera 12.16 being quite a bit slower and Opera Next being even slower than that. In addition, the odd page seemed to load exceptionally fast on SeaMonkey, but took particularly long on other browsers (betanews.com was one example). There was less than a handful of sites I found that did this however. If anyone is interested in testing this out to confirm/refute, I would be interested in the results.
