I've been using Flying Dutchman Polar blades since the 90's. And yes, they do seem to cut slower than other blades. A couple of years ago I start branching out beyond the Polar to Penguin Silver and they seem to do better on stock up to 1/2", at least better than the Polar. I also started using Pegas MGT blades (3's and 5's) and they do so much better on everything over 1/2", especially the hardwoods (like yellowheart, Purpleheart, Bloodwood and such) But that's my experience! (your results may vary (LOL))
So for me I keep FD Polar for thin stuff and Penguin for slightly thicker and the Pegas for everything over 1/2", but blade is a personal choice and there is no one right answer to that question. Find what works for you.
I also have a Bauer (My #3 saw) and I upgraded to the Pegas blade holders. Huge improvement as far as I'm concerned. As for cutting, for me all 3 saws "cut" about equally as well, but like @Denny Knappen mentioned, vibration is a big factor. My Hawk is rock solid with no vibration at all, the King is close behind. My Bauer is close with the only issue being the start when I hit the pedal, there's a pretty good "clunk" which i feel in the table and results in a bit of vibration for a few seconds.
Hope this helps a little.
