Simple... either one :-)

FontLab has gone the way of Macromedia. Use Glyphs.

If they have never worked with a font program start with Fontographer and move up to Fontlab. Glyphs is the newbie and is interesting but is not yet the industry standard like Fontographer or Fontlab.

Will there be Glyphs available for any format other than Mac? Not everyone's a Mac owner or user...

@glyphsapp said on Twitter (Oct 3): “Sadly can’t develop for Windows and have no resource to hire one to do it. So no Win version for now”.

Both. There are some things Fontographer simply does better than FontLab, and vice versa—for me. Your needs and work habits may differ.
