Spiderman is one of the last good (and full featured) pins from Stern before they went into 3 years of cost cutting mode.
I would be going the Spiderman on the basis it more than likely won't be run again, and it will hold its value in the medium term.
5-6 tops for the SM, by the way.
8950 for the blue Avengers LE which apparently drops to 6400 two weeks after you take it out of the box.
The seller ran the risk of an auction and got burnt. Good on him for being one of the few sellers on ebay who would've let this auction run to the end.
I don't think you will see too many Avengers LE sell for a similar price.
As for the SM vs Avengers, i think i'd take the SM, but they are way over priced.
