I'm very out of date so take my opinion with a grain of salt. The customer support I received from F5 when they acquired a telco product was about the worst support I've ever seen. Now this wasn't the general LB equipment that F5 has the reputation around, it's some specific equipment for LTE networks.
We'd get completely bogus explanations for bugs, escalate up the chain to VPs and leadership because there was an obvious training, understanding, and support for complex issues problem, and get the VPs trying to gaslight us into believing their explanations were valid. We're talking things like on our IPv4 only network, the reason we're having issues is due to bugs in the equipment receiving IPv6 packets.
So it's one of those things where I've personally been burned so hard by F5 that I'd probably to an unreasonable level look for other vendors. The only thing is, this was awhile ago, and the rumor's I've heard are that no one involved is still employed by F5.
