I could agree with his argument on the Les Paul. I've never owned one myself ( one of two styles I'd like to own, along with a V ) but I have actually played a few Les Pauls over the years ( unlike a V). As a kid, that was like graduating when you got to play one for the first time. It's bigger and heartier feeling than most, very thick sounding yet smooth and not abrasive. They even look more sophisticated and elegant when you compare them with most Fenders ( which I started out on one in a Tele). They had much easier necks and fretboards.
I ended up floating towards SGs however for a long time starting out. It was like taking a Strat and it's double cutaways, but making them sharper while incorporating the humbuckers and most of the neck feel of a Les Paul. Sort of a nice compromise between the two. These days I jump around on guitars, but I still love an SG as it was my main guitar for nearly a decade. Still would love to get a Les Paul sometime though and even a nice V!
As for the P-90s? That's something I have NEVER played oddly enough. I totally dig the sound they give, which is smack dab in between a Fender Single Coil and a fat Humbucker. I've even thought about tinkering with an old Epiphone G-400 I have ( first guitar I bought on my own after being gifted the Tele on my 12th birthday) and completely stripping it down and rebuilding it with P-90s like a poor man's Tony Iommi build
