Copper pipe flow meter install

I’m going to be installing my meter in the next couple of days and was wondering how critical it is to use the Sharkbite brand of coupling. I went to my local plumbing supply store and they carry Tectite vs. Sharkbite. I’ve included a picture of the package and the inside of the coupling. It says use with CU/CPVC/PEX and the store said it should work. I have my doubts, though, so please let me know.

Thanks!
