What XLDVee said. if the bow company is competing in today's market, they are all good bows. some are surely better than others, with their own strengths. the most important thing is that it fits you well and is comfortable and fun to shoot. if it fits you well you are more likely to shoot it a lot and practice a lot, thats what it takes.
but to answer your question, i only know one person with a mission, and its a youngsters bow. it is a nice bow though, and i have shot a mission, just forgot what model it was, but it was set at 86lbs. the fit and finish isn't quite as good as my outback, but i liked the bow.
