CAVE2

In CAVE 2 all the models feel a bit bigger than they are in Unity on my laptop. For example garbage cans are as tall as you are, standing in the middle. This happens because you can see your own body in CAVE2 and you can get a good estimation of objects' sizes. I wish I had initially tried my project with CAVE2, then the models would not be as big.

CAVE2 provides a bigger field of view comparing to VIVE, but still it is not as wide as real life.

You do not have to wear a heavy headset to use CAVE2 and honestly I think it's glasses look cool.

You can have multiple users in CAVE2 and collaborate with them, only one of you should lead the way, but the rest will be able to see what others are seeing.

CAVE2 definitely has a better image resolution, but since you can see the gap between the monitors and walls and roof, it feels less immersive (at least it won't give you nausea).

Finally both VIVE and CAVE2 give you the opportunity to fly around the campus which is not yet a possibility in real Grove.
