Barbed fittings: Good or bad?

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?
Yes I use the "PUSH ON" stuff all the time but be sure that you get "PUSH ON" for both the hose and fittings and DO NOT clamp these you can buy the hose for pretty much any application you need MSC Industrial Supply is a good source or any PARKER store
