Flowrates is an important aspect in pump performance and heat dump, another aspect of pump performance, is not mentioned as much.

A modded DDC will have nearly matching flowrates as D5 and similar PQ curve.

note D5 is a slightly better performing version of D4
Laing DDC + TDX (nozzle1) = 9.7 LPM (mod top)
Laing D4 + TDX (nozzle1) = 9.5 LPM
Laing DDC-1Plus + TDX (nozzle1) = 10.5 LPM (for top inlet with alphacool top)
DDC 1plus will outperform the D4/D5 pump. DDC mod is equal to D5

Heat dump is second factor not mentioned in either of those articles. Lower heat dump from the mcp 600/aquaexetrme-50z allows it to perform as well if not better than D5 pump. I think a modded DDC will outperform D5 both due to less heatdump and having similar flowrates. I think the modded DDC Ultra extra flowrates might offset by additional heatdump but not sure how much.
