This question is reminiscent of when people post asking what the "best" blade steel is. The honest answer is that there is no "best" knife. You need to determine what attributes you want it to have, and then go from there.
You stated it will be an EDC knife and you want a good quality blade. Do you want something that is exceptionally corrosion resistant, one that is very hard with extreme edge-holding capability, one that is very tough, one that you can sharpen quite easily, etc.? There will always be some sort of compromise involved
Next you mention a solid handle. Do you want something with metal scales, reinforced plastic, G-10, wood?
What is your lock preference? There are lock-backs, frame locks and liner locks, locks such as the Ball Bearing lock or AXIS lock, and others. All should be more than sufficient for EDC usage, but some are easier to manipulate and some people like certain types more than others.
The point is that there are quite a few excellent knives that fit your initial criteria, and none of them could universally be considered the "best" out of the bunch. Personally though, if you are seeking a good, all-around folder, I would suggest looking at the Spyderco Delica or Endura.
