Your comment points out that there are a lot of variations in what each of us need based on our beard type (fine vs coarse), and out skin type (sensitive vs less so).
Someone with a tough beard and less sensitive skin can use the very sharpest blades in the most aggressive razors. It sound like you might fall into that category.
Someone with a fine beard and sensitive skin might like less sharp, very smooth blades.
Someone with a fine beard and less sensitive skin can use nearly any blade in any razor.
I have a tough beard and sensitive skin. I like using the very sharp blades (Feather, Nacet, 7 O'Clock Black, Israeli Reds, German Wilkinson Sword) in less aggressive razors.
In aggressive razors like a Muhle R41, I avoid using the sharpest blades as they are too harsh. In that razor, I like using mid-sharp blades like Crystals, Gillette Silver Blue, Polsilver, Voskhod, 7 O'Clock Green and Yellow, Astra SP and Personna Lab Blue.
Blades like Merkur, VDH, Shark Super Stainless, and Derby Extra are not sharp enough to cut my tough beard without tugging.
As you can see, I have tried a lot of blades. Thus, I highly endorse the blade sampler suggestion.
Trying a lot of different blades in different razors is the only way you can learn what works best for you.
