@flyboynm - To answer your questions specifically:
Alternate "Mesh" Products - Presuming you really must have an all-wireless setup and absolutely cannot hard-wire any nodes, Eero is the best bang for the buck, hands down, provided, of course, 200-300 Mb/s per wifi client is enough for you (which it usually is, in the vast majority of scenarios). Why do I say that? 1) it's
actual mesh (unlike all other "mesh" products in the space, laughably), 2) it uses QoS that actually works (fq_codel between nodes; CAKE on the gateway's WAN interface if internet is <500Mb), 3) it can re-purpose radios for front/backhaul duty and re-channelize all links, near-instantaneously, based on real-time traffic and RF analysis. You may be thinking "great... so what?" Well all I can tell you is that stuff actually
does make a difference, and no other whole-house product I'm aware of comes anywhere close to the same amount of "it just works" factor. You can certainly find higher spatial-stream radios out there (Orbi tri-band or AmpliFi Alien come to mind), but they're effectively being run by "brain-dead" software stacks in comparison to what Eero is doing -- again, when we're talking about
all-wireless deployments. So if you upgrade to anything from Velop, IMHO go Eero, or figure out a way to hard-wire and do controller-based, wire-first APs (UniFi, Omada, Cisco WAP, Ruckus, etc.).
Pre-draft AX vs AC - In the consumer "mesh" space specifically, IMHO it isn't worth the premium right now; I'm not aware of any options that are reliable enough. That may change in the near future, but I try to buy -- and suggest -- what works
today, not what will hopefully work soon enough. Also, I'm pretty sure Eero will wait until 6E spec clears to release a next-gen offering. For all-in-one routers or APs, however, that's a more stable area, and really depends on how many AX clients you have, and if you do have some, how badly you want the supposed throughput gains that come with an AX/AX client/station pairing. That said,
all the other AX-unique features such as OFDMA (the big one), BSS coloring, target wake timing, etc. are effectively
vaporware in terms of actually being implemented and enjoyable by a user base, and will remain so for some time (many months, at least). So overall, no, pre-draft AX gear is typically
not worth it for most setups
right now (be they home, SMB or enterprise for that matter). That may change in the next year, but by that time, Wifi 6E spec may be closing in on draft 1, and the "gen 1" Wifi 6 stuff will just have to be ripped and replaced to support the extended 6E spectrum. So if you're faced with the choice of saving cost for largely equivalent performance (in most real-life scenarios), you might as well wait. That's my two cents at least.
