Having owned and used several of these, I can say that like most other things, each design has its pros and cons.

2-post lifts give the best access under the car, but you have to bolt them to the floor solidly, which means you need a sound floor without cracks nearby. Once you install them, they are hard to move. They take up a lot of space because the columns have to be wide apart. But if there's enough shop space, these are my fave.

The "Maxx Jack" is a short version of the 2-post. I've used it, and the space under it is tight and you usually sit on a stool while working. I'd much rather be able to stand up and get a better angle and better leverage on things, or stand away from some spot I'm welding or draining oil from. However, if you don't have the overhead clearance for a higher lift, these are a fair compromise. They are advertised as "portable" but they aren't really. You must bolt them to the floor for use, and moving them involves removing those bolts.

4-post lifts are great for getting under the center of the car, and for creating another storage spot underneath. Most of them don't need to be bolted to the floor, and have attachable casters, so you can move them around the shop. They also take up a lot of room. But, the car is still resting on its wheels, so to do suspension or tire/wheel or brake work, you need a bridge with a scissors jack to raise the car off the treads of the lift. That's more complicated, so if you do a lot of that work, then maybe you should look at the other options.

Scissors lifts or Quick Jacks: These are great for working on suspension, wheels/tires, brakes and the like. They take up less space, and most of them are "portable" to some degree. But they block some or much of the center of the car. If you don't drop your own engine/trans then these are a good choice.

Side lifts or "1-post": since the lift column is on one side, it takes up less room in your shop. But the arms have to extend all the way under the car, so they restrict access under the center of the car. I haven't used one of these, but they look like the have more cons than the other designs.
