Abbadon is of course, very, very powerful, but I think some people who probably haven't read any HH or 40k books seriously overestimate him.

So to put it in perspective, Abbadon, even with his power bloated through chaos etc is still not as powerful as even a single one of the traitor Primarchs. This is because they simply began life, much, much more powerful than Abbadon. So you have a Primarch bloated by Chaos and an Astartes, pretty easy to work out the Primarch is still miles stronger.

So if a loyalist Primarch were to return they could of course defeat Abbadon, because they are a Primarch, so are inherently a lot more powerful than Abbadon. His chaos pacts of course even the odds a little but an Astartes can simply never be a Primarch, so if a loyalist did return, they would be odds on to defeat Abbadon one on one.
