Well said, Jack. Environment can have as much or more to do with how any wireless router performs at your location, than the router itself. That said, some routers do have deficiencies in some aspects; those can be avoided with thorough review of online comments and reviews, to note a pattern. For example, the particular $20 AC1200 router sold by TrendNet at Newegg, was noted to "run hot", even with DD-WRT installed. Well, I bought four of them (on two different sales for $20 ea), to have some DD-WRT AC1200 routers, and yes, they run REALLY hot. So much so, that I would be concerned to deploy them in a client's location. Three of them are unopened, might just resell them for what I paid for them. They do work though, and they are DD-WRT capable, maybe someone will buy them.
But other than obvious lemons, most routers do have similar performance, if they are based on similar technology platforms.
SmallNetBuilder has excellent router reviews and ranking charts, if anyone is interested in comparisons.
Basically, look at their chart, find a router that meets your WAN-LAN routing speed needs, or wireless distance needs, and pick a price point and look at the models around there.
Edit: That said, I consider myself a "SOHO router veteran user" (as I am sure Jack is too), having have used a 802.11b router, and NIC, 802.11g (and SpeedBooster), 802.11n 150Mbit, 300Mbit, draft and final, and 802.11ac 1x1, 2x2, 3x3, as well as DD-WRT, Tomato, Netgear, LinkSys, Asus, TrendNet, TP-Link factory firmware, and wireless client, client bridge, WDS, and other things.
But I have yet to use one of the really high-end "Super" routers ($300+ class), with multiple 5Ghz AC bands, etc.
My most advanced router, that I am also currently using, besides my FIOS-supplied router, is an Asus AC68R, that I bought refurb off of Newegg on ebay, for a very reasonable price (compared to new). I subsequently put on Shibby Tomato 138. (I had been running Tomato on my Asus RT-N12/D1 N300 router previously.)
I like it, it has been mostly stable. Performance is fine.
