Great job by both. I am really impressed with the work, not only in this matchup, but in the league as a whole.
The size differential hurts 98, I think given more space, 98 could have really put itself over the top here. As it is, there is no identifying text as to who it is ( I know it Ironman but others may not). I think the scan lines are great, not too much at all. Great job!
While I really like 99, I am not a fan of a lot of text. Call me stupid or whatever, but text shouldn't dominate a piece in my opinion. However, I love the spiderman logo over the top of the city and the backshot of spidey, gives it a flair of the dramatic. Great Job!
Overall though, I think I am going with 98, although both of these blow anything I do away.
