I'll say my 2018 GTI is damn excellent at pretty much everything...braking, handing, great seats, great ergonomics, pretty quick etc. I enjoy knowing it will do whatever I want it to and do it well. That said, I find it not terribly exciting to drive, probably BECAUSE it is so good, so solid, so quiet, so without any drama.
My 32-year-old Porsche 924S has a few rattles and lousy door handles (ironically, they are from a VW), but it makes all the right noises from the engine and exhaust, and while it's not as "easy" to drive as the GTI I have no doubt at all it can take corners faster (both cars are on the same tires in the same width, incidentally) and can stop faster too (even if the brakes dont' "feel" as good as the GTi). There's something to be said for a car being lightweight, and that's something that few new cars are. No matter how good you tune the suspension or add power or put on big brakes, the laws of physics still apply. And I still LOVE driving the Porsche, while the GTI is simply "nice to drive and very good"
Likewise, my 31-year old Dodge Raider is in all measurable ways a hunk of junk compared to modern SUVs, hell even my 2005 Sequoia. It leans, has mediocre brakes, is pretty slow in every respect, and street handling is best described as marginal. But I'd rather drive it any day than my Sequoia or my wife's (excellent-handling) CX-9 or any other new SUV (or new Jeep, I might add).
There's also this general sense of pride driving an old car (especially an uncommon one). I can drive my very nice GTI and nobody will take a second glance at it, since ther are 100 others just like it within a 10-mile radius (that goes for things like an M3 in this area, for that matter). But in the Porsche or Raider, I constantly get people stopping to ask about it, or talking about it at the gas station, or whatever, which is kind of fun.
IDK, I have no desire at all to do my daily commute in any of my classic cars (or other classic cars, no matter how nice). Modern amenities make boring commuting much nicer (heated seats, bluetooth, auto wipers, etc etc). But when I'm not driving to work, I almost always leave the GTI parked all weekend and drive the Raider, Porsche, maybe the Sequoia, or even occaionally the e30 rally car (though it has NO amentities). They are all more "fun" to be in than the GTI, for various reasons.
(when I had my moderately-modded WRX, I probably considered that a more "fun" car, but that's because it had a number of flaws, like a vintage car that it had to make up for by being "fun.") . At the time I did not have the Porsche or the Raider, though....so my only "vintage" options were my then-beater rallycross e30 with a weak M10 (yawn) or my 1990 XJ (which amazingly drove far lousier than the Raider and I hated driving it).
Classic cars aren't automatically "fun" to drive. Some just suck. But if you get the right ones, they'll beat out a new car for pleasure driving any time.
