I feel the same way.Both have a place and have strengths. Neither is strictly better than the other, only better for a certain application. There are also a great deal of other alignments besides just sealed and ported.
I have owned excellent sealed, ported and PR subs in the past. The best happened to be the JL Audio Fathom F113 which is sealed but I have heard in a showroom a pair of Wilson Audio XS Subs and they blew my mind and are ported.
Aerial makes and excellent ported sub as well so I think the designer and builder have a lot more to do with what makes a better sub than just ported or sealed.
For DIY I prefer sealed so far as watts are cheap now and the enclosures are easier to make. I have never built a ported sub but have made a PR design which I am going to compare to the same driver in a sealed box. I definitely need to make a ported sub soon so I can see if I am missing out.
