I personally have been fascinated by woodwork all my life. It is so impressive how one can turn a brown cut piece of a tree into something that is either mechanically utilizable or aesthetically pleasing. A lot of companies have to deal with wood, not just carpenters. Along the way of that, there are a lot of tools that come in handy. In my opinion, there are two things that affect that outcome of woodwork; craftsmanship and the tools used.
Art Without Brush
Cutting edges of a wood without quality tools is like a knight fighting with a stick, or an artist painting with a stick. No matter how good you are at your job, the tools will bring in a big limitation if you cannot get ahold of something with quality worth.

Of course, having all the right tools but not the best swordsman to yield them would be equally useless. However, in the industry, I believe that there are plenty of artists but just not the right brushes for different strokes.
If your blades are not quality enough, or if you are using the wrong one for the job, then the finishing of the end product will always have something missing. The only way to avoid that is if you keep all your tools in check, especially the dado blade.
A dado blade is one of the most important part of both cutting and refining whatever you have just finished working on. This is why I always tell my fellow woodwork men to go with dado blades that are of high quality, that come in different diameters, or maybe get a series with chippers and the whole set of different ranges of dado blades.
