It's a great distro but if you want to have more solid experience you could consider do these things

1- install LTS kernel alongside the normal one (especially if you use nvidia) because who knows what would happen in newer bleeding edge kernels .

2- some people like to use timeshift (I don't use it personally but it's recommended) and it's better to make btrfs disk .

3- don't use aur unless if there is a package that you can't get by official repos .

Other than that I feel like it's pretty stable distro and fast but please you have to consider doing these recommendations (from my personal experience)

I hope you enjoy your arch (endeavour os) experience .
