I personally love halo 3’s chopper, it’s like a futuristic battle harley! 
I really hope it returns to halo 4.
I love the scorpion and the Grizzly from Halo Wars.
If the falcon could’ve held people in the passenger seats then yes. Unfortunately, it doesn’t. Maybe in Halo 4… I choose Warthog!
Well call me a giant noob but I like the Gauss hog. I loved the days of dominating in halo 2 with it and on halo 3 (the map the the big satellites on btb heavys) and on reach (break neck on anniversary BTB). ha! now looking back on it I used that thing way to much and was the only thing I would mount the gun on!
You know those Hawkes in Halo Wars, they are badass!
I love them.
From Halo Wars the powerful “Cobra” and from Halo 2/3/Reach the M12G1 LAAV aka. Gauus Hog
Warthog, it will remain my favorite (most likely) Halo vehicle for all time. I hope they create a new variant in Halo 4.
Brute Chopper of course
The transport vehicle that will be in Halo 4
(Yes there will be one, 343i has confirmed our dreams)
Scarab
The Mongoose
The banshee, warthog and the falcon are all very fun to drive around.
Banshee
Elephant. For the splattering

This is the best description of the Chopper I have ever read. Well done.
As for my favourite vehicle, I’d say it’s the Scorpion… because, well… Tank beats everything.
Clearly the only correct answer is Mongoose, especially if armed with passenger carrying plasma weapons or snipers.
Falcon’s a close second for me, then the Gauss. 
The Sparrowhawk’s successor using Infinity Tech. Oh ya I went there at mach 7 and into exo-space with a nose mounted laser more powerful than a Sentinel’s. Unfortunately you can’t see me due to its cloaking ability. And you can’t shoot me if you could thanks to an AI controlled bubble shield (with manual control)… You can be MY wingman anytime.

Definitely This!

Link?
And the Gauss Hog. So much PWN, it’s the only reason I like Heavies.
The Hog, What else ?
