I would say that playing both 4.e3 and 4.Qc2 is the most instructive to learn.

If I had to give only one recommendation, it would be for 4.e3, mainly because of its flexibility, as I mentioned in my previous post in this thread.
MNb has stated before that he likes the Hubner Variation as Black against the Rubinstein, but White can avoid this with 5.Nge2 or 5.Bd3 Nc6 6.Nge2. And against the move-order 4...0-0 5.Bd3 c5, White should consider 6.d5!?, as played by Korchnoi against Karpov in Baguio City. However, there is nothing wrong with 6.Nge2, which is certainly not 'completely innocent', as the 6...d5 7.cd5 cd4 8.ed4 Nd5 9.Bc2!? system (delaying castling in favour of Qd3, h4 and a kingside attack) shows.
Generally speaking, the Bd3/Nge2 system is the most tactically aggressive, the Nge2 system is the most positional, and the Bd3/Nf3 is both tactical and positional depending on how both sides play.
Finally, if White wishes to play the Samisch against the Nimzo, I would recommend that he does so via. an 4.e3 move order, e.g. only playing the Samisch against 4...0-0 and meeting 4...c5 and 4...b6 with something different.
