@pipiwa4312 I hope this link helps explain the difference between Chrome and Chromium for you - https://www.howtogeek.com/202825/what’s-the-difference-between-chromium-and-chrome/

It was written in 2018 so may not be accurate now but it gives a non-tech overview. Also you may be interested to know that Chromium is used by a heap of the major browser suppliers. Here is a list of 10 I found here - although the 'best' will differ based on the definition being used to say something is better than another (being 7ft tall is best in the NBA, but far from the best if you are a jockey 😁 ):

Google Chrome
Microsoft Edge
Iron Browser
Epic Privacy Browser
Colibri
Blisk
Brave
Vivaldi
Opera
Chromium.
