Cons
Con Still based upon Chromium/Chrome
Can yield to bloat if clogged with too many plugins and apps from the webstore.
Con Has some CSS issues on some websites
Has problems loading Sourceforge.com
Con Stores your history/settings into google servers
Con It spies on you
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Con Sometimes outdated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.
