Bravado is much better.
Hands down, Bravado is much better. Who needs a stupid compensation truck, an ugly muscle car, or the worst super in the game?
Trust me, I'm a special member. (For the moment)
I hope that when you say ugly muscle car, you're talking about the Dominator. And I'd have to say, I agree. However, the Blade and Hotknife are amongst the sauciest cars in the game.
On top of that, a large part of Bravado's line-up consists of vans, and while vans are cool and all, there's not too much you can really do with them (excluding the Youga, but who wants a two-seater van?). Vapid's Speedo might have Bravado's vans beat as it's modded features actually stick after being insured in online.
Now, Bravado does have the Rat Loader and Dune Loader, both of which are fine vehicles. The Gauntlet is eh, and the Banshee's aight at most. Sure, they have the Buffalo, in my opinion it's nothing special. Most people have one, including every YouTuber and their mothers.
But Vapid is just so much more diverse. Like I said, you have the Blade and the Hotknife, both very fine vehicles. They almost nailed classics, especially with the Peyote, the most perfect lowrider in the game. Then you have the Bullet - not my cup of tea, but I'd rather have it over most of the supers we have in the game. It just looks better, as well as handles better (as far as I remember) at the sacrifice of it's top speed.
Then you have the always-loved Sandking, aka the Compensator because anyone who owns one is pretty much a fruit with little-to-no dong. There's also the Saddler and the Bobcat, but nobody uses those anyways.
Then you got Vapid's own minivan. Also whack and unfavored, yes, but a must-have if you're the kinda guy that drives a Faggio around for everyone to laugh at. Can't forget the Stanier, which if I remember correctly is based off a Crown Vic. That's a fun little sedan, has a decent speed to it after it's pimped out (as well as having the ability to look like an undercover cop car).
Aesthetically, Vapid wins. Performance-wise, Vapid still kinda wins. Not at the same time, but in the long run.
