What about their switches? I'm looking at buying a small 10GB SFP switch and TP-Link was one option.

I've already got Ubiquiti kit, and frankly while I don't much like it I can't deny that it works well enough and is reasonably priced for what you get.

So, it looks like I'm going to lean towards the Ubiquiti switches.

It really depends on what you need from it; a cheap L2 switch will do the job, but frankly, you can get a Ubiquti Flex Mini with 5x1Gb ports for £35, I have a bunch of them around the house, and they're semi-managed so I can do VLANs on them and power them over PoE; since I'm already running Unifi, don't see the point cheaping out on switches.

I also have a bunch of EdgeMAX because I use the L3 features, they were more expensive, and that range is sadly now discontinued, but the Unifi equipment have all been workhorses, and the only think I've ever had fail in the past decade was an EdgeRouter Lite, the power circuitry failed after some dodgy mains voltage issues in my previous home.
