I like both and own both. Started with DA/SA & 1911. I'm a strong proponent of learning the DA/SA or DAO configurations along side the striker / SAO platforms. Being able to proficiently handle the DA/SA & DAO is almost like learning to drive a manual shift car. Yes it's a little harder to learn at first, but once you learn it, you can drive any car. Or in this case, shoot any pistol well.
