My old CIJ jag was ‘97 I think, I’d assumed it was the 9.5” radius but maybe it was super comfortable cos it was the reduced radius. I don’t know.
Some people prefer the rounder 7.25, others like a flatter one. Typically the rounder ones are more comfy for chords, flatter if you do leads. Hence why compound radius necks are also a thing. Best of both worlds.
Then again, Billy Corgan's a bit of a shredder and when he had a signature strat from Fender around the time of the Zeitgeist album, which stock came with a 70-style head, and 9.5" radius. A few years later, when he was touring Oceania, he'd switched the necks out on his live guitars with 57 reissues. He said at the time as the Smashing Pumpkins were playing a lot of old material, he found those necks better for it. then he was bringing out his blue Mellon Collie 70s strat on tour again.
Here's some terrible photos of my guitars, starting with my Jag:

Stock except for a taped-up Mustang bridge. I know the Jaguar bridge is meant to rock back & forth with the strings, but I've found I get on better with a static Tune-O-Matic like my J Mascis Jazzmaster has. Want to get some fuzz & reverb pedals and play some shoegazey stuff on this one.
My most recent one, a Gordon Smith GS-1 60:

I really wanted a Les Paul Junior-style guitar, and Gibsons were either too expensive, or 2nd hand 2015 models (the ones with the weird necks & robo tuners). Epiphone hadn't unveiled their "Inspired by Gibson" line either, which has a proper set-neck Junior in it. This was £569, which for a hand-made UK guitar, is really good. Great punky machine, this one. Nicknamed "Maiko-chan" because I'm a wanker that named his guitar, after the sticker I got while in Japan earlier this year.
And if course, my pride & Joy, my Edwards Les Paul:

Swapped the pickups out a couple of years ago for Bare Knuckle Emeralds, and it became my favourite-sounding guitar. Absolutely nails the Manic Street Preachers & Sex Pistols tones I got it for, plugged into my Tiny Terror (an amp Orange should never have discontinued). Took the pickguard off, have since lost the screws, kinda like it this way.
