Hello Stovepipe and welcome to SRP.
For me there are too many favorites to pick a brand that stands out.
It's like asking what is your favorite child.
However there are a few basics on which most SRP members will agree.
Like size, your first straight should be between 5/8 - 6/8's width for handling and maneuverability.
Tip should be rounded and not a sharp spike. (for obvious reasons)
Most importantly your new vintage razor needs to be "shave ready".
Might add should be of a respected brand, Dovo, Ralf Aust, Boker, Puma, Ern, Kropp, Bengal, and so on and on and on..........
