I used the drop ear type that you showed in your second pic. That allowed me to use conventional brass nipples and stops under all of the sinks. I have a home run pex system, and with all the issues with bad brass fittings in the pex world, I wish I hadn't.
I've not had an issues but those are my one weak spot. I don't anticipate any problems with the tubing. If I did it again I would probably bring the pex out of the wall with those metal stud to stud brackets.
