Does Prep27 cover more exams?

Their list adds OET and NCLEX-RN, a nursing licence exam. Hilingo's OET is on its way, and Hilingo covers TCF Canada, which Prep27 does not.

Is a 99% score correlation realistic?

A correlation figure cannot be checked from outside, so we show the working instead: every Hilingo score is broken down per criterion, per word and per sound, and you can see exactly where each mark went.
