  So which scheme is best – UNT/Michaels, Ghestem or Questem? Let's start by tabulating the final contract using each scheme; assuming a weak hand and no further opposition bidding and see where we eventually end up: -

Notes: 1 The Michaels bid is ambiguous for the minors.
  2 Ghestem stays lower than Questem.
  3 Questem stays lower than Ghestem.
  4 We cannot bid Questem 3 with the very strong hand type.
 
     
  So which scheme really is best? If you are loathe to give up your normal 3 bid then you have to use UNT/Michaels. But you have no bid in 2 situations and it's ambiguous in the minors in four situations. Very big minuses in my opinion.  
     
  Assuming that you are prepared to use 3 conventionally then it boils down to this: -  
     
 
-

Questem has the very big advantage that over a 1 or 1 opening you can cue bid to show

  both majors and rest at the two level. Thus making it fairly safe with 5-4 type hands in the same way as Michaels. Very handy for those of you who like to make noises with weak 5-4's.
- Ghestem has the advantage over Questem in that you can always bid 3 conventionally with
  the very big hand since 's is never one of your suits. Since this comes up far less often than the weak 5-4 major suit type hands I think that Questem is to be preferred. Up to you.
