In terms of features and performance there is little to choose between Google Chrome and Firefox. The main difference is access to Google services. Chrome is much more tightly tied and so those connections work better but many are unhappy at so much of their data being shared with Google.
As @parkdale I use Chrome, Firefox and sometimes Edge when I have to, some sites only support a subset of browsers. My browser of choice is Opera. Two prime features are VPN and built-in ad blocking. The latter is more efficient than the extensions available elsewhere. (I whitelist Kitz.)
