Here are my 2 cents, I have rushed into buying MikroTik without previously comparing a lot and missed few points because of it and because of the old "if you don't know what's good, you know what's expensive" and I got myself hAP ac.

First it's one great "machine". WiFi is incredible. MikroTik as it always was is awesome with all the settings and features but the things that i don't like with hAP ac are:

- at some point I moved from 50/50 Mbps speed to 960/880 Mbps, first it worked OK and lately I can't really hit the top speeds (is it FW or OS update?, I did not change anything special in my architecture and/or Firewall/NAT rules, did not add any more users than I had, CPU is not overloaded...)
- it's one core CPU (my mistake in comparing it)
- 16 MB of storage, cmon MikroTik...
- 1 Gbps connection in between CPU and switch
- price

I like:

- SFP Cage (increase costs if you need it but can increase throughput)
- 3 chain WiFi

I suggest hAP ac2 because of ARM architecture, 4 cores CPU, (I think you don't need the SFP cage). There's 2 chain WiFi which is pretty much enough, awesome price and 2 Gbps link in between switch and CPU so theoretically it should support 1 Gbps internet speed if you have one.

If you need an affordable router go for the hap ac2, if you need a good wireless device think about it twice. I cannot recommend anythink really apart from the good old rb2011 for your 2G network. I use my hap ac2 primarily as a router, moved the 2G network back to my rb2011 and all my 5G devices connect mostly to my wap ac. I think you should consider a setup with more than 1 device, especially when it comes to 5G.

Hap AC2 + an SFP port =
