Buying a Pixel 7 Pro, install Custom ROM or stay on default?

I've been using China/Xiaomi Phones for the longest time and hated the installed Android Version because all of the clutter, bloat and privacy concerns. Now I am about to buy a Google Pixel 7 Pro.

What do you guys think, is a Custom ROM needed or should I just stick to the Default with Adguard and Disable some Google Apps to get a similar Experience?

Just hoping to get some Opinions. :)
