memphis belle or Diamond d7152 and d7104?

I am deciding which set up i would like to run.  I have 2 sets of diamond M361 componets rate at 60w RMS and a brand new 10w6 D2 dual 4 ohm sub.  I am wondering what would be better, I can either run a D1752 600x1 @ 4ohm to my sub and a d7104 100x4 @ 4ohm , or run the memphis belle mch1300 which is 75x4 @ 4 ohm and 300x1 at 4ohm.  The memphis can also run to 1100x1 @ 1 ohm in the 5th ch.  The advantages of the D7's I believe are better power and SQ but i i have limited space in my 350Z and the amps are a total of 42" long combined, so i would have to put in amp racks.  The memphis is cheaper and is a lot smaller.  What set up should i choose?

Bang for buck......
