Gillette ProGlide Shield Razor Refills for Men, 4 Blade Refills

Like this? https://a.co/d/00Mt4Gri I ask because it would be a lot cheaper in the long run to get something like this ( https://a.co/d/04D4a7cQ ) and buy a razor that accepts blades like this. I use the leaf razor which is definitely expensive up front. But I pay pennies for the blades. It takes 2 blades which cost 8 cents every time I want to replace them.
