If you mean platformer on Armor games instead of "latform armor games" I recommend the unfair platformer...don't rage quit though ;P. But if it counts the best/highest rated platformer is Raze 2, it's on platforms...I think it counts.
I agree with Monsterblood12. Cactus McCoy is one of the best platform games I've found on this site. And I also think that the second part is better than the first one.
