I think both are fine folders but in this scenario I'd go with the Sebenza hands down. IT has both a stronger body and a stronger lock.

I don't think this is exactly what I would call a fair comparison. They are both frame locks, and while Strider and Emerson follow one school (less contact area) and CRK follows a different school (more contact area) I don't think it has ever been diffinatively proven which way is better. If it were, then everybody would make them the same.
As far as a stronger body, that is debatable as well. The Sebenza is all titanium and the Strider is half Titanium and half G-10. I think that the PT's Titanium half is thicker than the Sebenzas. G-10 is also not all that far behind titanium in terms of tensile strength (depending on the Ti alloy). Plus they are differnt shapes, so really which one is "stronger" is going to depend on a lot more factors that just one being all titanium and one not. And I can't imagine either one not being strong enough for anything but extremely heavy abuse. I doubt you are going to actually break the handle of either. If all that we were worried about was stregth, knife makers would make frame locks out of hardened steel or tungston carbide or something. There are a lot of materials that are stronger than titanium.
All that being said, I think which one to get really comes down to personal opinion of the asthetics of each knife. Whichever one you think looks better is the one that you should get. They are both plenty tough, and will both perform above and beyond the call of duty for an EDC. The sebenza is going to slice a little better, but the PT is a little burlier. Depends what you like / want. As far as smoothness, the Sebenza is going to be a little smoother. Much smoother when knew. The PT will take about 500 - 1000 openings for the detent to wear through the bead blast on the blade, after that they will be pretty close. A Buck Mayo TNT will still be smoother than either of them, IME at least. Heat treat is generally thought of as better on Stiders than on CRK's, but I don't think that is really anything to worry over either.
Both companies have great warrenties, so if anything goes wrong with either knife, you don't have to worry about it as either one would more than likely be fixed for free.
Personally I like the PT better, but that is based on style, as the way I see it, they are pretty much equal in all other respects.
Edit: DGG, while the Military is a great knife, based on size alone, I don't think it is a very good substitute for a Strider PT or a small Sebenza. Even the Para is significantly bigger than both.
