Might I recommend the "throw ball" teleportation like budget cuts. That seems to have the best balancing for emergency movement. Insta-click-port feels like cheating, and the same would go for blur sprinting (also one of the sickening ones)
Fair enough, I enjoy not having ingame locomotion and rather relying on my own floorspace (2.3m x 1.8m for me) and plays really well with that.
I can see issues with people who don't have that, but 2x2 seems to be the standard
Also adds a good element of danger and urgency by not being able to run away
