There are 3 things you need to do:
1 - What the devices you have need to connect at the best speed for them?
2 - A site survey
3 - What router's features best match what you learn from steps 1 and 2
1 - how new are your devices? Are they 2.4 or 5 Ghz? G? N? AC? And yes you can list them here and we can look them up but I'd advise doing the research yourself.
2- this is easy on your phone get an app named wifi analyzer - look through the screens for 2.4 and 5 Ghz channel selection to see what the saturation is around you.
3 - Then with the info you learn from 1 and 2 look at the features of the routers in your price range.
I am not now nor will I ever tell someone what to specifically buy on the internet. If I knew you it'd be different. If you get the info and post it then post a few routers that you aren't sure which is best, that would be different. Pro and Con type stuff but to say "You pick for me" NOPE.
