I'd like to first say I don't think Addictedtogear's comment was meet to be taken so harshly. It was more of a funny jest then an insult.
On to the question...
Pros tanto, Easier to sharpen, you can drag them on a flat surface, no bending of the rest to get a proper even sharpening, assuming of course your sharpening your knife in the traditional method, or on the bottom of a coffee mug or something. You can set the grind angle of the front to a different angle than that of the belly. They scrape stuff really really well. The front tip may become dull like any knife, but I often find what has aptly been named the second edge, the point where the front edge meets the belly edge is sharp. This makes for a secondary point that can be used to make very precise cuts. The penetration things kind of a myth, if you pry straight on with a tanto the tips actually narrower and unless it's reinforced it's weaker than many drop points. If however you pry using the whole front tip so that the edge is laying flat you get allot of prying strength. Drop points tend to be better slicers than tantos, for instances if you had to cut allot of rope an emerson commander would probably be better suited for the situation than a cqc-7. For EDC use a drop point is considered the go to knife, not that tantos aren't adapt for the task, I personally can be found rocking a super CQC-7 most days and find it works great for the tasks I run up against in my life. I particularly like how quick and easy it is to sharpen.
