I actually posted my opinion about Hummer VS Cybertruck this morning in another post for somebody. I just noticed this thread just now so I'll cut and paste...
1) I ABSOLUTELY LOVED driving around in the summer with the T-tops off in the Hummer. However, they leak and creak the rest of the time, not horrible but it is a compromise. GM offered to fix the leak and maybe they are built better now.
2) Both trucks are the best riding trucks (dare I say vehicles) that I've ever ridden in. The Hummer handles very well considering how much it weighs, however, it will remind you how heavy it is anytime you have to grab a leg full of brakes. The Cybertruck FEELS lighter and more nimble because IT IS lighter and more nimble.
3) Neither truck have confidence inspiring brakes but the Cybertruck can stop faster (albeit with more pedal effort).
4) The Cybertruck is definitely quicker and has a higher top speed. This is HUGE for me as nothing says, "Bad Ass" more than that.
5) The steering of the Cybertruck just totally blows every other vehicle I've ever driven out of the water!
6) I love the stainless rock sliders on the Hummer as it makes getting in easier and they are very SOLID!
7) I did NOT like that there are studs sticking down through the underbelly of the Hummer waiting to get caught/busted off on stuff.
8) I LOVE that I don't get bugs splattered all over the windshield of the Cybertruck where the Hummer gets it's own, little bug graveyard that you have to look through. Bird droppings are a different story (I live in Seagull Shitville. In fact, I'm the MAYOR of Seagull Shitville).
9) I always worried about leaving the Hummer in the parking lot, the Cybertruck not so much (even though the Cybertruck gets WAY more attention).
10) PARTS! Parts for the Hummer are CRAZY (like $3500 for a tail light assembly).
11) I liked the visibility from inside the Hummer much better than the Cybertruck.
12) Infotainment system in the Cybertruck beats the Hummer hands down (although there were some cool features I liked about the Hummer that Cybertruck doesn't have).
13) Hummer has a kick-ass rear view mirror. Cybertruck needs a mirror like that WAY more than the Hummer does and yet, hmmm....
14) Hummer has the camera view from above which I loved, Cybertruck does not. Hummer also has cameras to see under the truck front and back with little built in washers. That kicks ass. Cybertruck has Sentry mode though and that rocks!
15) Both trucks have kick ASS sound systems. I think Cybertruck's is a little better.
16) Hummer I think is a little classier where as the Cybertruck is more about satisfying my inner child.
17) Cybertruck gets a whole lot more negative reactions from people (but a lot more positive ones too).
These are some of the major things from my experience and opinions. Overall I like the Cybertruck better.
