For what it's worth: Anvil-style road cases are super durable, offer great protection, and look cool. Admit it. They are what we see touring rock stars using. They have groovy stencils and sticker and stuff.
But they are expensive, heavy, bulky, and overkill for what most of us do. Also, they are heavily armored and unforgiving; anything that comes into contact with a flight case will lose hit points - even other flight cases. If you've ever seen in the inside of a passenger vehicle that has transported flight cases, it looks like a badger got loose in there. I have been a professional musician for over forty years, and while I do appreciate the utility and protection of a genuine flight case, I almost never use one any more. Modern plastic cases are tough, waterproof, and offer nearly the same protection at a fraction of the cost and weight. The only time I use an Anvil-style case is when I'm handing off my gear for freight / air travel, and even that isn't every time... remember: you pay for weight / size.
For me, the main point of a case is protect its contents against pretty much any predictable encounter, while allowing a normal human like me to still carry that case by myself. I suppose that means one day something of mine might get damaged because it was only "well protected" versus "really really well protected". It's a reasonable tradeoff when I'm handling my own gear.
