Before I make any comments, I want to mention that I cut mainly thicker woods 3/4" to 1-1/2" . So my observations apply to that on my Hegner Saw.
What you cut and the saw you cut with are all part of the equation for how different blades cut.
I find that the MGT blades are aggressive for me. They seem to want to cut on their own. They are great for cutting thicker material as are the PS Woods Super Sharps. I know that many people use the FD ultra reverse blades but they do not work for me in the thicker woods. The teeth are not big enough to clear the saw dust efficiently.
I use mainly FD Polar blades and do not notice the drift that some describe. I do not even think about drift but just concentrate on following the line.
I also will slow my saw down at times when I am cutting detail in thicker woods. I recently cut some of the compound reindeer that were just over 1/2" tall and ran my saw very slowly to get the cuts done properly. I just do not have the control on such small things with high saw speed.
I pay attention to the blade number especially when cutting puzzles. If I am cutting a Judy Peterson puzzle from 3/4" wood, I will use a FD Polar #5. This gives me a clean cut with the right amount of kerf so the pieces fit together nicely. A #3 blade results in tight puzzle pieces and a #7 loose pieces. I also find the higher the blade number the more difficult to cut tight turns well. The other thing is that the type of wood also makes a difference in how the pieces fit. Maple gives very clean cuts and the pieces slide easily. A puzzle cut with the same blade from poplar or a softer wood may be tighter.
But, everyone has their own style, type of work and type of wood and one needs to experiment to find what works best for them.
