after i played against raptor some games i cant say its way better than the Storm raven,
Storm raven has more dakka infantry and Superior AT shots Especcially BA. Plus its a transport too.!
Raptor is good cause can split so many shots i think 4 targets by itself! (1 POTM, 1 each gunner and main target)
But except the 7 shots s6 ap 3 in front there are just some more s7 shots not bad not good either, In my opinion i would only go for a Raptor if i was to play against many flyers aka necrons which s7 is good, or against msu, extra good raptor has its 4HP,
