Wait, people think Jeeps are good? XD

That aside as another commenter alluded to you are better off defining what type of riding you are going to be doing. There are so many different types of mountain bikes with different geometry and components each tailored slightly towards different disciplines. If you get a decent bike with good components then of course you can use it for different kinds of riding but it's best to choose one that will be optimised for the type of riding you'll be doing the most.

For example gravel bikes will have the geometry of a 90s MTB, with drop bars and some skinnier but grippy tyres designed for dirt and gravel tracks but not particularly heavy hits.

XC bikes will be light and designed for a long time in the saddle, often with suspension but shorter travel to soak up some bumps but not designed for hucking off massive drops.

Trail bikes will have a more slack geometry designed for descending fast and taking bigger hits but won't be as comfortable climbing.

There are many others too but once you figure out the kind of riding you want to do you can then look into what bikes are considered the best within that category, it will help narrow your search a lot :)
