Push-pull with yateloon's vs push with Gentletyphoons

[Megamilkz]

I currently have a 2x120 rad with push pull on the top of my haf 932 in a cpu only loop. I am adding a gpu block and a 4x120 to the bottom of my case (the power supply is in the drive bay) I am stuck between taking off 2 of the fans from my 2x120 making both the 2x120 and the 4x120 only pull, OR i could buy like 8 yateloons and keep the 2x120 push pull, and also have a push pull on the 4x120, keep in mind the yateloons would probably be lows and the gentletyphoons are the 1850rpm ones
buying 8 yateloons would be about 40 bucks, vs buying one more gentletyphoon which would be like 20 bucks

Based on what I have read elsewhere, I would guess that the YL push-pull would slightly outperform the GT push. However, I don't think the difference would be very significant.

the cost is enough for me... Yates win every time you factor in cost
