I'm using a HPPS in my under-desktop box.
It's very quiet - as far as I can tell, it's actually quieter than the 1046. It certainly vibrates less.
The body is the same size as the 1046, impeller is about the same width but I think it's a bit larger in diameter.
The only comparison I've been able to find online is from watercoolplanet.de (this is a site with erm... questionable block ratings - although maybe they do actually line up this way at very low flow rates).
The spreadsheet is mostly specs from the manufacturer, except it appears they did do a couple of tests themselves, including measuring flow rate through 2m of tubing at various IDs (10mm, 8mm, 6mm) Here's that data extracted:

Code:

	     10mm ID	  8mm ID		  6mm ID
1046	   4,075 l/min	3,337 l/min	1,692 l/min
HPPS	   4,796 l/min	3,894 l/min	2,359 l/min
1048	   5,313 l/min	3,982 l/min	2,328 l/min
L20ll Pro   5,138 l/min	3,559 l/min	1,946 l/min

I would guess that these were done correctly (how hard is it to time flow into a bucket?)
If I had my act together, I'd at least try to convert these flow rates into actual flow vs head-restriction numbers, which could then be graphed. Guess I don't though (sorry)...
