I have both, but I primarily use p411. I like it's interface and features much better than Date Check. I also think there are regional differences in which has more of a presence.  

I like to describe p411 as the Cadillac and Date Check as the Chevrolet.  

I'm sure some of the gals will chime in from their perspective.

Welcome to the playground.

providers can indicate if they are newbie friendly on their profiles.  Date-Check does not.  DC is cheaper for a life time membership.  Many guys have both, I do.  They each have some advantages.  If I were you, I'd try to get verified on both.

I use p411 most often and I get feedback from some of my clients that they prefer it over dc.
