Maybe this reveals my preferences, as some systems I suck at and some I do well in.  Anyway, here are two phases  of my d4 repertoire and the ordering that you ask for in each phase.

Phase 1-

1.QGD Exchange-theoretical darling, overwhelming choice of elite players vs. pure QGD move order.  I suck at it though; I would groan every time I had to face it.

2.Semi-Slav Botvinnik system-I really flopped in the complications for some reason on the White side.  I do much better here with black. Weird.  Something about seeing  that triangle of pawns in the semi-slav produces a reaction of awe and respect (maybe fear!?).

3.QGA Nf3 Classical Systems- not good at the IQP here.  I like to be black instead.

4. Nimzo e3- I used to start feeling in my games that black was actually better in these positions.  Not a pleasure for me.

5. Slav- I really enjoy playing vs. the Slav actually, with both Ne5 and e3.

I made some adjustments, here's phase 2:

1. QGD Catalan- I do WAY better with the Catalan, but it is still a tough opening for me to face.

2. Semi-Slav Anti-Meran Qc2:  Thank you Sakaev, I've found my calling.  Still a difficult and complicated setup to face, though.

3. QGA- e4: I like playing vs. the QGA in this line, even the endings.

4. Slav- mostly gone from my Nc3,e3 move order. Sometimes I use the reg. move order though and play the Dutch system.

5. Nimzo Qc2- LOVE this opening from both sides of the board.   

I guess a short summary of my tastes is this: don't like IQP with white, prefer flexible or open pawn structures in the center, with one exception: the advance french center (d4,e5 vs. d5,e6) that sometimes I can get in the Slav/Classical/Dutch variation or the Anti-Meran Qc2  quiet lines.

1. I avoid the Nimzo, I take the Bogo if it comes and I like playing against the QID with g3 and a pawn sacrifice on d5, you get a long lasting initiative with pressions on the center and many black players feel uncomfortable in such situations.
2. QGA: I do not like to play against it but I do not try to avoid it. I try to go the catalan way. It is difficult to get some influence on how black will play, so you have to be patient when trying to find a plan.
3. QGD: I like to play against it and I use the catalan. You can get some complications on the Q-side but you have also (very) good compensations in the center and may have the opportunity of starting a strong K-side attack.
4. Slav: Difficult to play against someone who knows what he is doing. I try to the black white-squares bishop off and to get some play on the c-line with possibilities on the K-side.
5. Semi-slav: I like it. I try to go for Qc2, Nc3 and g4. You can get wild games and, as many black players choose the semi-slav because they want to feel secure, they are not comfortable in such positions. 

You 1.d4 players. What do you say about the Slav/Semi ? and about the Queens gambit accepted/declined or the Nimzo-bogo-queens Indian.

Could you give and order of what defences you least would like to face. 

like      1. Nimzo-bogo-QID    2. Queens gambit accepted  3. Qgambit declined 4. The Slav 

5.Semi-Slav


and a short commentary of your choice.

It would be very interesting to hear about that.
