I’m thinking about replacing my older mid size truck with a reliable, capable, and enclosed vehicle.
All three are capable and enclosed. Only one is reliable, and that is the Toyota. Caveat - talking about 5th generation and older 4Runners. Jury is still out on how dependable the new 6th generation will be with the turbocharged 4 cylinder engine and all-new transmission.
I've been a Jeep owner longer than most people have been alive. They are the most capable off road because of the articulation and the strength of the solid front axle, and can be easily lifted if you want to run 37" tires. But the other two are not far behind. The Jeep Rubicon gives you both front and rear lockers, as does the Bronco Sasquatch package. 4Runner Off-road models come with rear lockers but they also have ATRAC which works pretty darn good for the front end.
I follow the forums for all three and I find one thing telling. The Jeep and Bronco forums mainly spend their time discussing all the problems they are having to fix. The 4Runner forums are mostly discussions about the mods they are making to their rigs.

From the Bronco forums:
Both Jeep and Bronco seem to have electrical/electronic problems - and they are loaded with electronic stuff. Can't even get a manual transfer case shifter in the Bronco. How'd you like to be in a remote location in a place where you need 4wd and the vehicle tells you it's "Temporarily Disabled"? Is it really so difficult to pull a 4x4 lever? Have a buddy here who just got rid of his new Bronco. Door windows on the Bronco have no frames around them - makes the doors easier to store when removed from the vehicle. On his Bronco, at freeway speeds the windows would pull away from the seals causing horrendous wind noise.
I currently own both a Jeep Rubicon and a 2022 Toyota 4Runner. The Rubicon I take ONLY when I know I'll be going into some really gnarly terrain. I use the 4Runner for everything else. For dirt roads and trails where you're not actually rock crawling the 4Runner is the better vehicle. More comfortable, more room inside, better ride, and I know it will get me there and bring me back without breaking down. And it will never experience "death wobble" which seems to be a thing even with new Jeeps.
