I have the ARB hydraulic jack as well as a bottle jack.
The ARB hydraulic jack is large, heavy, and takes up space. The recommended storage is "in the vertical position" when not in use, but I have it lay horizontally in the Braptor when I'm out wheeling. The best place I've found for it that keeps it secure and out of the way is conveniently under the rear seats (assuming you don't fold the seats down). It's a perfect fit there in the carrying case it comes with, it stays put and doesn't interfere with leg/foot room for rear passengers.
I have a bottle jack from Safe Jack like the above poster also mentioned, specifically the
6 Ton 'The Sergeant' Off Road Kit. It comes in an ammo case, which is nice and compact, but I created foam cut-outs for it and now have it in my rear drawer system so it doesn't rattle around. Here are some pics:

Space for gloves to lay on top of the bottle jack:

Enough space to put the Braptor toolkit and another storage pouch on top. This drawer has most of the recovery gear I carry:

As far as use cases for each type of jack, based on real-world experience:
- A bottle jack is better when you need to get a wheel off the ground to change the tire because you can position it under the axle and easily raise a corner of the vehicle (doesn't flex the suspension)
- A Hydraulic jack is better when you need to un-wedge your vehicle from something where getting under the axle is not an option, usually you're not lifting a tire totally off the ground and need to create space between your vehicle and what you're stuck on -- much harder to lift the wheel off the ground since you can't position it under an axle due to its size, so these aren't ideal for changing tires but it's still possible
Pro Eagle has a really great Co2 bottle jack:
