I've read now twice that they are the same art(just a matter of preference to which title to use when referring to it) and have read the counter argument that they are in fact different(different forms here and there, structural display different, speed different,etc.)

The later variables such as speed I sometimes notice are different between practitioners per se.

Hoping someone w/ expertise or who has studied both more than dabbling could add anything? Thank you.

Best,

P.S.-Besides Tai ji mantis and Mei Hua mantis--you've also got the TJ-MH mantis. Confusing at times.
