Solo. The supporting characters are normally enough for me to enjoy a solo book, without the inclusion of lots of other characters. I prefer to get really involved in one, at max two, characters at a time in one book, opposed to a whole team.
I picked team. I like the interaction between the characters and over all team work of it. I like teams of 2 the best it is just more fun in pairs.
I hate it when a team gets to big and they can't seem to focus so I say no more than like 10 members give or take. I think less than 10 is best but that's me.
I read solo stuff too but the best stories all ways have a gust star.
Solo. I feel that way allows better character development.
Mainly this reason. Team books are good but a lot of times it feels like the story is being dragged just so each member can either resolve their differences or succumb to more drama.
