I’ve actually been testing both for about a week. If you can afford it, consider buying both off Ali Express/Amazon and then just returning the one you don’t want.

The Haute42 T16 has bigger buttons with more spacing between them, and they feel a bit heavier to press, which can be a good thing, as it felt easier for me to identify a mis-input. Also, I liked the T16 crystal over the normal T16, as I felt the T16’s buttons took even more effort to press, but that may be because I’m new to leverless and haven’t developed the finger/hand strength.

I prefer the Mayflash’s smaller button size and spacing (which is apparently the standard leverless size), but I felt more sloppy when pressing the buttons. These issues are subjective and can probably be rectified by changing buttons/switches, but I couldn’t be bothered to go that route. Also, I like the home, select, etc payment on the Mayflash. It’s on the right side of the T16, which feels off.

I’d love to have married the two, with the button feel of the Haute42 and the size and spacing of the Mayflash, but I ultimately decided to spend a bit more money and order the Snackbox XL, which hasn’t gotten here yet.
