FPS means nothing.
Barrel length, build quality, the quality of the inner barrel, quality of the hop-up, and the quality and weight of the BB's is what makes the difference.
Almosty any gun can be a good outdoor gun. Personally, for outdoor, I prefer something with a long barrel like a G36, M16, G3, or bullpup (AUG, L85, FAMAS). However many people use M4 varients.
