No, they aren't the same but they are similar. The basic principle of operation apply to both designs. It looks like they offer similar advantages:
1) unobstructed tube (seal is outside of the tube)
2) allow higher pressure than barb & clamps
3) no damage to the hose from the clamp so no leaks over time.
The major differance is that the swage fittings use metal ferrules instead of the o-ring and collet in the push-in connectors. I don't know which is better, since I haven't used the push-in fittings. I'm guessing the push-ins are easier to use and the swaged fittings are better at higher pressure. (But I hope nobody is going to be running a system at over 10 atmospheres of pressure, so the push-in should be fine.) A metal swage connection might last longer than a o-ring, but Nitrile rings quite good. They look like pretty good connectors to me.
I'll bet either one will do fine. I would choose either one over a barbed connection.
