What you are saying can just as well be Gravity Suit = Mirror Shield, Plasma Beam = Light Arrows, Space Jump = Wings of Pegasus. In order for both to have been released when they were, they must have been in production around the same time. I don't know what point you are trying to make though. Does it in any spectrum of reality matter which was the spiritual sequel of the other? What are you even trying to have said? Nothing? "Essentially a spiritual sequel" is essentially the same as "Not a sequel"
I wasn't really making a point, just noting that the games were extremely similar and referenced each other. The equipment thing refers to the fact that, in Zero Mission, Samus finds the Gravity Suit, Plasma Beam, and Space Jump earlier in the game and can't use them until the final level, in almost exactly the same manner as Pit finds the sacred reasures but can't use them until the end. Seemed like a shout out to me. Kid Icarus also had some Metroids in it (under a different name, though.)
Doesn't matter in the slightest, I just like that kind of random trivia.
Same, but it seems the Silver Armor isn't noted as an item in the first game, while it is in the second. Same general function, but Pit does not recieve the mirror shield in the second game. Still, Pit's sprite has the armor in the first game, so it looks like he has it.
I meant limited in that Samus does not have her usual arsenal. The original Metroid has fewer weapons and items than any other game in the series, hence she's limited compared to the usual. Zero Mission has likely replaced it in the canon completely. Pit, on the other hand, doesn't have as many other games or items, so sticking with the first doesn't limit him as much as it does her. But you're right, in that it's unnecessary to think of what each doesn't have.
True, Pit has the air advantage, unless Samus can jump high enough to Screw Attack him. However, using the environment isn't as good as it could be since the wave beam will bypass walls completely, as will the light arrows. Cover is only going to be useful in obscuring sight, since both Pit and Samus can shoot through it without a problem.
