I had a Luxul ABR440 router, Luxul PoE switch, and a Luxul unmanaged switch all put in by my dealer. I had sporadic issues, so I took out the router and PoE switch and replaced them with an edgerouter lite and a PoE edgeswitch and it has been rock solid since. I left in the Luxul unmanaged switch because it looks great in the rack and I haven't had any issues with it.
The premium price for Pakedge/Luxul is just not worth it IMO. With that being said, read up on the Ubnt gear. It is not for the faint of heart, it's not plug and play and there are occasionally firmware bugs such as 5.4.9 for the UniFi AP line that was released then pulled a few weeks later.
