From my experience, these cheapo Unifi switches from Flex series are bad.

They heavily drop frames under even moderate loads (well under 2gbit). If you turn on vlan tagging, they won't hanlde more than 0.1gbit.

They work well if you need to connect a bunch of slow iot devices. Don't dare connecting them to a desktop.

The Ultra series of utility switches is rock solid though.

That’s not been my experience. My flex has been rock solid and it’s outside.

Try to tag a vlan on a port and pass some heavy udp traffic through it.

		I'm a "big tagger", and I have no problem with it. I don't control the type of traffic going through it, though; from my understanding, TCP/UDP wouldn't make much of a difference?

Same, works great on my end, not seeing any poor experience like this.
