it depends on the motor. My engine has vtec, but it's shitty SOHC vtec, not the balls to the walls DOHC vtec.
Same idea with i-vtec. On the K20a3 (rsx and civic si) the motor opens all of the valves, but barely opens one, so in essence under something like 2300 rpm, the engine is running on 3 valves. After the engagement point, all valves are fully open. If you ask me, that's more similar to the old school e-vtec. The k20a2 is old school (rsx type-s), 3 cam profiles, righ revving, vtec around 5k. Nuthin like the old 5500rpm kick in the pants. I think it may also incoporate the other technology that the a3 has as well but i'm not sure. so in a nutshell, i-vtec is good and bad depending on the motor. a2=bitchin a3=leaves something to be desired.

It's simple. I-vtec is better because it has an "i" in front of it.
 Honestly I don't have a clue...but usually when a car company adds letters to something it becomes more technologically advanced.

haha...Apparently, I-VtEC was supposed to be Honda's answer to Toyota's VVT-i. Like JDM said, it all depends on the motor setup in order to determine which VTEC is better.

my opinion,
DOHC vtec (like in gsr's and type r's b18c1/c3/c5) will never be replaced. It's just better hands down.
