The DM Pro is a route I looked long, and somewhat longingly, at.
I settled on the Asus route as something of a judgement call. Why? Well, it's not a solution aimed
entirely at the non-tech user. I mean, the router controls can be pretty intimidating to an absolute novice. Getting it set up isn't a walk in thev park for the novice, but it's do-able.
The UniFi struck me as really something that really is for someone that needs, or wants (and can afford) a somewhat scaled back professional/commercial grade of system, both in the money they're prepared to invest, and in the time and learning curve they're up for .... unless they're already somewhat grounded in that area.
There's always a balance,
IMHO, between how complicated a piece of kit is, with versatilty versus complexity. Either something like Asus (or Netgear, TP-Link etc) is rather more versatile but rather more intimidating as an 'enthusiast' router than a vanilla ISP-supplied box, but doesn't go as far as the UniFi end of things. I was willing to spend
some time learning a bit about configuration but, only up to a point. Fiddling with the settings is, for me, very much a means to an end not an end in it's own right.
All told, it's one never-ending balancing act get it set up to suit ME, but that's nowhere near saying it'll suit anybody else. Different needs and priorties will dictate a difference approach. I'm offcoally jealous of the UniFi gear, by the way. NIIIIIICE.
