Tone is taste. Some love Gibson "thickness", others hate it's "muddiness"
That history thing is baloney. They were the MAJOR good guitars until the 80's, so anything before then doesn't count. Since then, yeah, many people still love them, but many guitarists are also "vintage buffs" for no good reason; there's nothing about a Fender or Gibson that a Yamaha, Heritage, Hamer, or other make couldn't dupe at the same price point (well, except psychologically). And since the 80's PLENTY of great rock has been done on non-fender, non-gibson guitars.
As for value, well, OK if you're into collecting. But percentage is kind of misleading. You'll lose every bit as many dollars on reselling your overpriced gibson as any other brand, and lose more right off the bat when you "drive it off the lot".
As you say, buy what you want & love it. I never understood the gibson "thing", but obviously many people do.
