Had the Gladiator been available when I was shopping, I would have given it serious consideration. I did in fact consider a Jeep but was turned off by the mileage and when the salesman said they still had trouble with roof leaks. Being a Jeep, the video was dead on when it said the aftermarket is huge, whereas while the aftermarket has expanded for the Colorado, I doubt it will ever truly catch up with that of the Jeep.
Overall, I would say the comparison was well and fairly done.
This applies to me as well. When I heard Jeep was coming out with a pickup, I wanted one. I've got a 1975 CJ-5 and it's a hoot to wheel, but it sure isn't long on creature comforts. When I found out that the Gladiator would be offered in crew cab only, it was a deal breaker for me. I wanted an extended cab (or regular cab), so the ZR2 was it for me. I don't regret the decision, either. It's been a super-fun truck!
The major issues they raised with the ZR2 are fair (towing capacity, low shock mounts, hood causes visibility issues) but in my opinion are somewhat easily rectified. I've already installed the shock skids (which are a huge plus) and I'm going to be installing a front camera next, so that will hep alleviate the forward visibility problems to a large degree. Towing capacity didn't register in my book, as I don't anticipate doing any towing. One or both of the reviewers complained about the high bedsides on the Chevy, but the only time I've had my bed full of actual loose cargo (not counting moving furniture to/from apartments, etc.) was when I was hauling firewood and I'm quite glad that the sidewalls are the height they are, thank you very much. I also feel like they downplayed how maneuverable these trucks are, because I've been through some tight stuff in Moab and had no issues whatsoever.
Some positives: I do like that you can (supposedly) fit 35s with no issues, and you can get the 110v outlet in the bed. I also like that they kept the 4:1 Wrangler Rubicon transfer case ratio for the Gladiator Rubicon. I like that you can still do the Jeep thing and take off all the doors, pop the top and drop the windshield.
All in all I felt that it was a mostly fair review; there was perhaps some Jeep bias, but it is the new toy in the sandbox, so it will get some well-deserved recognition. They definitely didn't hit all of the Chevy's bells and whistles, either, but many of those are known inclusions anyway. Personally, I don't particularly love the final overall look of the Gladiator, but throw some accessories on it and slap 35s on it and my opinion would probably change. :)
I do hope to see some out on the trail, though. That will be cool.
