Your mileage may vary for performance. It really depends what OS and what hardware. In my experience saying all BSDs are slower at rendering would be too broad a statement.
If you’ve done Arch and Debian server installs, you’ll be fine installing a major BSD. Just answer prompts and you are done, particularly if you are using the default disk partitioning scheme. Consider NetBSD. It’s known for its wide hardware compatibility. X is pre-installed, just “startx”.
My experience is the same, but it may be that the anti-adblock measures are still being tested on specific demographics and we are in the lucky group (for now).
