I don't have one favorite. I have some that I prefer to others but it just comes down to the shave I am in the mood for on any given day. Some favorites, and in no particular order:
Gillette NEW (both short and long comb)-DE
1907 Ever-Ready lather catcher-SE
Schick Adjustable Injector-SE
STAR DE-DE
Gillette Super Adjustable-DE
iKon Shavecraft 101-DE
GEM 1912 Damaskeene-SE
British Ever-Ready Featherweight-SE
There are probabably others that I have forgotten to mention.
