Typically watercooling is only nominally better,take for instance the closed loop cooling craze that went on with pcs, for the same price one can get a Noctua NH-D15 that would outpreform most clcs. A good heatsink plus a high static pressure fan almost always does better for cheaper.
Now back to the topic, I have been looking at the crees and it seems like the cxb2530 performs quite well for the price, keeping in mind i have 9 drivers on the mars ii 1200 meaning that would be 18 lamps. Going with either the 3050 or the 3590 would be almost prohibitively costly in the most expensive case costing nearly $900.
Consider the 72v 3590, 1 per driver. For $40-45 per, you get 56% efficiency. 2 x 3070 are 59%, 2 x 3590 36v are 64% efficient at .7A. All top bin.
And consider the driver waste as well. The mars drivers are only ~85% efficient, compared to say a 95% mean well. So a 56% efficient cxb3590 at the wall turns into 48% on a Mars driver, 53% on a meanwell.
