I use Beseler with good lens that allow for 4x5, medium format and small format - the full-meal-deal so to speak.
It sounds like the choices you have are fairly good.
Make sure parts are not worn out or missing!
The movements should be smooth and I think good ... very good lenses for enlarging are a significant factor to darkroom practice.
Also think about the amount of work you plan to do in a darkroom versus the cost and what you get for your investment.
