You will probably get a hundred different answers to that.
You would probably get a hundred different answers if you asked for a definition of a "tactical" folder, too.
Personal preferences (blade design, tip-up/tip-down carry, handle material, size, blade steel, lock mechanism, plain vs combo vs serrated edge-for example) shape all of our perceptions of what is "best".
That said, my personal favorite is the Benchmade AFCK.
If offered with an Axis lock (which would make it ambidextrous) w/tip-up carry, it would be MY idea of perfection.
btw, as long as we are talking about production knives (which are usually "reasonably" priced), I don't think price should be a huge issue when you're talking about something that you will carry and use daily. If you go cheap, you'll probably just end up buying that one you really wanted later, anyway

Those are of the knives I own. Can't comment on ones I haven't tried.
