Are Schicks better than good old double edged razors, or is it mostly marketing spin? They do point out one of the things I like about injectors though; the ease of getting the correct angle. Simply place flat against the cheek and shave.
If I were to recommend a classic safety razor for a new wetshaver today, and s/he didn’t mind buying a vintage razor second hand, I would put a Schick injector near the top of the list simply due to the ease of learning it.
