I love my Sebenza. Actually I have a love/hate relationship with it because it's such a great knife... on one hand it is wonderful to carry and use, on the other hand it means my other (really great) knives get so little playtime.
I agree with you that the Spyderco Tenacious is an excellent value but I will have to disagree that the serrated edge is better for bushcrafting as it is harder to carve with the chisel ground serrations (or any serrations for that matter). I think you will find that the Tenacious should hold a great edge even when beating the heck out of it... I have never had to resharpen a knife in the field, and don't intend to ever have to. Spyderco is definitely my favorite brand as well, and I have spent an absurd amount of money exploring Spyderco's great selection of knives. Personally my favorite Spyderco for the outdoors is the Military or Paramilitary, and for urban use my favorite is the Caly 3 CF/ZDP.

I too love Moras... the knives are amazing, extremely inexpensive and great performers, my top choice for woodwork. The stock sheaths are terrible but better than nothing, so I recommend asking your sheathmaker of choice to make you a nice leather or kydex replacement.
Bonus points if you can name all the knives my hiking buddies and I took on a recent daytrip...
