For pleasant experience I would highly advice Vive. It has best tracking response with its base stations. Full 360 tracking while Rift got 2 cameras that hard to adjust as they on stands. Some dont like the trackers/controllers of Vive for their shape.
Oh yes! Batman is a great experience. I wish they made full length game like that
Skyrim VR- Its such an adventure and the immersion into story and action
( This is must have and my personal favourite )
