3 bpip - sluggish (probably because it also collects browser fingerprints) (this is very dangerous for privacy of users)
Every website that you visit collects all browser fingerprints in it's log files - it does not slow down anything. If BPIP is keeping and processing such data, where is it and why? No one cares if xx% of browsers are Safari, or what your preferred language is. Remember, if you were to hide all data from a webserver, no cookies would work and most modern sites would break.
These three services provide different types of data:
BPIP (created first) - is like the census. It collects, aggregates and compares data, ranking and sorting.
Loyce Club (created second) - is like a library. It contains RAW information which is harder to find but downloadable.
Ninjatastic Space (created third) - is like a registry. You can search for specific data if you have parameters.
