Some of my observations. All vehicles that were developed originally on Soviet Union are incredibly cramped inside, ergonomics are poor if any exist. On the other hand newly designed vehicles in Poland or purchased from our NATO allies are very comfortable. It's easy to get in and get out from Leopard 2 tanks, and it is very comfortable inside, still you need to watch inside to not hit some internal components, might hurt you!
From soldiers I talked with, there is only one ergonomic problem with Leopard 2's, and it's minor one. Because loader is responsible for radio's and operate them, an because radio's are placed in the turret rear, he might have problems to reach them during movement when main gun is stabilized because of that huge deflector for propelant charge stub cases that is attached to the main gun. Other than that, no problems.
SPH Krab is huge outside, and huge inside! A very modern vehicle also, you get inside and there are multifunction flat displays for gunner and commander. Overall it is also comfortable to get inside and outside through larger rear hull hatch.
APC Rosomak again, also very comfortable, I was actually surprised how large is space for dismounts in the rear (of course if you are not wearing ballistic vest and other stuff, and vehicle is largery empty, tough there is large storage area behind dismounts seats.
Interesting thing I noticed is that gunner and commander controls for the Hitfist-30P turret and Mk44 autocannon, are very similiar in concept of working mechanism to Challenger 2's turret controls. These are not joysticks that can move, there are small control knobs on them so you actually control turret traverse and main armament elevation by using thumbs.
And a video, not my tough, just found on YT.
