These are SLIGHTLY taller than Star Wars or G.I. Joe. Not by a whole lot, and depending on which character, they're very usable as custom fodder.
Personally, I love these. I wish they weren't $8.50, but they're awesome!
I picked up 2 more today, along with one that Wayne had sent me earlier this week, so I got Jean Grey, Warpath, and House of M Spider-Man
Jean Grey, the Jim Lee version everyone's been begging for for years: Disappointed. No neck articulation, so she's always looking down, and her face is so far off it hardly looks like her. She looks very uncomfortable.
Warpath: Probably my favorite figure in this line, period. Warpath comes from my favorite X-Team of all time, X-Force, and his new, darker version of himself in a much darker and deadlier X-Force is fantastic, and this figure is built SO well! I have nothing but praise for this one!
House of M Spider-Man: One of the few who knew the House of M alternative universe was false while he lived it, this version of Spider-Man was a celebrity, loved and admired by all. Uncle Ben was alive and well, he was married to Gwen Stacy, and they had a child together. It was Peter's greatest fantasy, yet lived in a nightmare. An excellent looking costume, very detailed and vivid. I'm not a huge Spider-Man fan, but I love this figure.
These are just short notations, not full reviews. Stay tuned for those!
