if you want just one grip I would either get; VKB MCGU, Virpil t-50cm2 or Constelation Alpha, Winwing F-16 + EX extension. VKB needs the VPforce passthrough adapter which imo is a good thing as you can still use the powerful vkb config software, Virpil is plug & play with the Rhino & WW needs an adapter but will then work with RHino base. Either one of those three grips will give you the most function, apart from a few aircraft like the Kiowa you'll be able to cover every single keybind on any hotas grip.
