Appreciate the reply and everyone has their own circumstances. But it doesn't sound like you've actually considered it or know anything about it which I guess is the basic answer to my question.
>Because the router I own is better than the router I don't own.
That's obviously not necessarily true. By this logic all upgrades for all time are pointless. Why get a better CPU/GPU/SSD? "The CPU/GPU/SSD I own is better than the CPU/GPU/SSD I don't own" after all. Except it's not, hence the interest in upgrading.
>Further, everything you describe is a bunch of complexity I don't need in my life.
Your setup sounds much, much more complicated actually.
>My time is too valuable to spend fiddling with configurations every time some piece of kit does a software update.
This isn't actually a thing. If anything, a core reason for using VLANs is precisely being able to just have any system at all and plug it in/join network and have it all be isolated and routing the right place with zero configuration.
>The way I do it, I plug a wireless router into one ISP, and a different wireless router into another ISP, and I'm done with it. Simple and clean.
Sounds complex and PITA, not least because it requires multiple ISPs and associated infrastructure, billing, tech support if needed, dealing with any security issues in their bottom barrel AIOs, etc. It's not free either, dual ISPs at least around here could easily add $400-1200/year. That's real money, even at the low end it's more money than a basic quality switch+router would cost.
