The performance bit is a lottery. Some people won’t notice any significant difference from chrome. A few will have severe issues. For most the slowdown will be circumstantial or won’t even notice.

Sites that don’t load properly are few and far between. Mostly poor web developers who are doing something undocumented or applying outdated practices. Often is just targeting some behavior that works on Chrome but is not standard. Firing up Brave to open the odd page once in a blue moon is not too extreme to ask. Specially since it’s the result of Google’s influence on the W3C standards and forcing their way upon others.

Brave iscool and all. But everytime I open it I fear it’s going to backdoor a cryptominer into my machine. It just gives that vibe.
