Definitely was a bad idea to rush Mistico onto the main roster instead of taking the time needed to let him learn the WWE style although I wonder if Rey's constantly getting injured ended up being a factor in rushing him to the main roster.
Hunico benefited a lot from the extra development time and low expectations than Mistico.

looks like no chance of a Sin Cara #1 vs Sin Cara #2 feud is going to be happening any time soon.
