A Gl.inet router is easy to use with it’s stock firmware. I recommend getting one and keeping it stock at least for awhile. You can still use Luci to get more in-depth while also having a simple to understand interface as a backup. It has Adguard built in as well as other things like VPNs and Tailscale and packet inspection. Of course through Luci you can install all sorts of stuff. The Flint 2 has good hardware to be able to run lots of addons
