Specs

Pros
Pro No telemetry
Pro Free software
100% Open Source and Libre.
Pro Amazing UI
Very clean and slick UI.
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.
Pro Auto imports setting from Thunderbird
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.
Cons
Con Few independent devs fighting the good fight
Although their work is to be fully commended, it can not be ignored that the devs of ungoogled Chromium are doing a massive task, and TBH waste their time while doing it. They're up against mega corp Google, reversing all the questionable stuff Google puts in Chrome to make them money. So David and Goliath, or a few devs in their spare time against "CyberDyne" if you will. So continuity might be an issue with ungoogled Chromium. Will it be up-to-date? Will it survive to see another day? Will the devs loose interest? The answer will most likely depend on your (previous) experience and scepticism.
Con Sometimes outdated
Con Still contains telementery
Default home page is telementery, and most websites are enabled by google.
Con Some websites think it is Chrome 80
As of today, many sites, like login.iready.com , might mislabel the browser as chrome.
Con Uses blink V8 turbo
It a old blink fork that is made up by nicwow.
Con Chrome clone
Ungoogled Chromium is a clone of Chrome, and since clone browsers are behind in updates giving a huge security risk, browsers like Tuga browser and Ungoogled Chromium should be avoided.
Con Uses a fake browser engine
Con Looks proprietary
Ungoogled Chromium is not that open source, but it might be closed source for windows 8.1 and below.
Con Difficult to install
Con Mostly just a customized Chromium build
Not much new here as many of chromiums features can be enabled or turned off with build flags.
Con Dependent on Google
Does not free you from big corpo.
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.
