What you pay a true premium for is when Shit Happens at 2AM and your network goes haywire, forcing the IT professional to rely on the trained technical support they paid a lot for and expect to get at 2AM in order to save their ass.
If you need trained technical support to troubleshoot an issue with a switch you aren't much of an IT Professional, IMHO.
In 20+ years in this profession I've never needed technical support on a switch for anything other than a hardware failure requiring RMA/warranty service. Cisco would certainly be less frustrating in this regard, because I wouldn't have to jump through the Tier 1 nonsense to convince them it actually is a hardware failure, as opposed to an ID10T error, but I haven't dealt with enough switch failures to justify the Cisco Premium for this scenario.
I could be a real snob and make the same statement about routers and firewalls. Admittedly a higher bar there, more that can go wrong configuration wise, still, unless we're talking super small business here, you should have enough in-house expertise to manage them with whatever configuration you need.
