Astra SP all day. Not the sharpest, but very smooth, last well, fantastic value, and they work well in every one of my DE razors. I have 100s of blades but having a good stock of SPs means I don't need to worry about future shaves.
I'm with you on the first three, and add:1. Gillette Nacet
2. Feather
3. Astra SP
4. Wizamet
5. Wilkinson Sword (Germany)
Since April I have been in the blade acquisition rabbit hole, mainly buying more of what I already had, but I have ventured out too. My current top five is:I do not yet have a top five but as things are now my order is:
1) King C Gillette
2) Dorco ST300 HQ
3) Tiger Platinum
I have a Dorco Titan in stock but still unused. Numbers 2 and 3 are somewhat interchangeable for me. I give the Dorco a point extra for longevity.
