I have tried the Platinums. Probably went through a couple tucks. I have also use Silver Blues. I much prefer the Silver Blues. So much so that they are my go to blades. I find them to give me the best combination of sharpness and comfort.
Gillette silver blue are a top tier blade for me, when I first tried one years ago it felt wonderful and many close shaves usually with minimal irritation. There are so many blades out there to make a person dizzy but a person can not go wrong with a GSB IMO. I made a ball park photo chart that might help some folks looking for a blade to try. I just found it easier to make a chart instead of describing the blade on other forums. Have some great shaves! stay & think safe in these times!
