I don't know that much about the spx but Brownig is managing Winchester now so that's a good thing. I just sold an 870, had it for 5 years and no problems I just realy liked the Browning BPS so I sold my 870. If you're a duck hunter take a look at th 887 I have a buddy that shoots one and he loves it. The Nova's are also good but for me it's BPS all the way.
