Those two models have
- 1GB network interfaces
- dual band WiFi
- 4 cores with good performance for firewalling or VPN at high bandwith
If you are looking for a cheap solution, I'm quite happy with the hAP ac^2 I have at a place with
a couple of users (4-6 devices) and upstream of 150Mbps. I'm not sure how well it will scale to
bandwidth closer to the 1Gbps limit, but I'm guessing that most providers will give more like 500Mbps of
real bandwidth when they advertise 1Gbps...
If you want USB (for instance for mobile backup) the hAP ac^2 has it. Its consumption is reasonable at 23W
The RB4011iGS+5HacQ2HnD-IN has a much more capable wifi, stronger CPU and chipset, but it is like 5x more expensive.
So take a look at the test results, your expected use patterns, your budget (electrical too, the RB4011 will draw double power),
I would not go for any MIPS mikrotik, as they are CPU-bound at such speeds for realistic firewall/VPN configurations. Any
ARM with reasonable switch chip will do. I'd recommend to use the test results as a guideline.
As I said, I expect a hAP ac^2 work reasonably for up to, say, 500 Mbps of real bandwidth, specially if at least part of it
is coming through cabled ethernet and not using WiFi.
