I’m a Personna person. Israeli platinum chrome, Med Prep, Lab Blue and the oft overlooked Crystal.
My favourite cheap as chips blade (was cheap as chips when I bought them 200 for £4.50) is the SuperMax TitaniumMy current favourites in no particular order of preference are:
Rapira Platinum Lux
Gillette Nacet Stainless
Wizamet Super Iridium
Personna Platinum Chrome
Gillette Silver Blue
I also like SuperMax Super Platinums that don't seem to get a lot of love but they work well for me and are cheap as chips.
