Also, you forget the self-upgrading part. Power Armor can't do that. And in addition, Spartans can use jetpacks, can turn invisible, become invincible with a EMP coming out that can push a helicopter out of the sky, deploy energy shields three times the strength of theirs, create holograms, run at superspeed, see through walls, deploy Autosentries, regenerate their health and create hardlight shields.

Asartes would be dead in seconds with proper application.

Astartes have jump packs too, in fact a third of your average chapter's fighting force will be assault marines who use them to get into close combat. That invincibility EMP is only good for a limited amount of time (the astartes will just wait him out and blast him soon as it's down) psykers can create holograms as well and they probably do have the tech to create holograms for distractive purposes, there are combat servitors to counter the autosentries, Astartes' power armor generally has a life support system installed to stabilize wounds, and they can do much the same regarding seeing through surfaces and running speed.

Just like a Spartan could kill an Astartes, the Astartes can kill the Spartan. Again, you also have to take into account that an astartes can be dozens or hundreds of years old, a Spartan's shelf life is only a few decades. The potential differences in their experience are enormous.
