Pros
Pro Not just an e-mail client
Seamonkey is more than just an e-mail client as it is a full featured web browser as well. This makes for a good app to use for those that dislike having many different apps on their devices as it is a bit like an all in one solution.

For those that would be making the switch from the Thunderbird e-mail client setup is quite easy with Seamonkey as it auto imports all previous Thunderbird settings.
Pro Customizable with Pale Moon and some Firefox addons
Supports add-ons from PM, Firefox and other Mozilla add-ons websites (xpi).
Pro All video formats supported
Does better than Firefox 52 in that regard.
Pro Supports Windows Vista
Pro Now supports pdf inside browser
Cons
Con Permanent CPU usage
Seamonkey permanently uses CPU (quite a few percents on a Intel i7). On a laptop this causes the fan to run (which make noise) and the battery to lasts less time.
Con Intermittent text distortion problem
Con Outdated
Becomes sluggish when surfing lots of hours, lacks compatibility with Firefox quantum add-ons.
