Mine is a gas engine. I mean sporty/fast definitely has something to do with it, although compared with other jeeps i've had it definitely holds its own even with the 37 inch tires. For me i'm a tall guy, and my eyeline is the very top of the windshield which is annoying, the bed bounce is really annoying on a certain stretch of my local highway, and a few other smaller things. The bronco fits my height and preferences better, the sportiness is there, plus my family history of bronco ownership compels me haha. My grandpa and my mom both had broncos back in the day, through the first few generations.
The gladiator is definitely fun but just not filling my needs/wants 100% like i thought it would. One drive around the block in that mannequin bronco last year had me sold on how much better it was for me, and it was a base model 4 cylinder haha. I will miss the storage space of the truck bed for camping though, I may have to get a little off road trailer for the bronco.
Also your C10 is gorgeous, I'd miss it too haha. I originally bought this truck to restore it and sell it but I love it too much now.
