One thing that makes it stand out is the role reversal. Instead of the usual male - led story, we have a female in the Peter Parker role. This can lead to different power dynamics and relationships with male characters. For example, her friendships or rivalries with male superheroes will be different.
A wicked beast manga might stand out for several reasons. The art style could be highly detailed and visually stunning. The story could have unexpected twists and turns that keep you on the edge of your seat. Also, the development of the characters and their relationships could be very engaging.
If the X - Men were in the Frozen universe, they would bring a new dynamic. Wolverine's healing factor would make him a valuable asset in the cold and dangerous environment. He could withstand extreme cold and any injuries that might come from the ice. Storm could collaborate with Elsa to create more elaborate weather patterns. The X - Men's mutant status could also cause some interesting reactions among the people of Arendelle, who are not used to such extraordinary abilities. It could lead to a story about acceptance and cooperation between two very different groups.
In my opinion, X Factor wasn't the best. There were other X-Men comics that had more compelling storylines and character developments during that time.
It's hard to say for sure. X-Factor had its moments, but there were other X-Men comics in the 90's that were also highly regarded. It really comes down to what aspects of the comics you value the most.
