Barbed fittings: Good or bad?

Sorry but tool man is incorrect the first picture is push on you can tell by the plastic ring and the shape and how many barbs

Yeah, I was just going to mention that - the fittings on the Oil Filter bypass fitting are the same style that Zombywoof identified as "push on"; the other 2 fittings are apparently just "barbed" as identified by Toolman.

BOTTOM LINE: Are any of you guys using these things on your engines? Or are they just "convenient bullshit" and I need to work harder at finding more OEM inspired stuff?
