D5 vs DDC vs EK VTX?

So this past weekend as I redid my tubes for the fourth time I discovered the OUT port on my EK XRES pump has stripped threads. The barb fitting just spins and doesn't tighten properly. There is shavings of acetal everywhere... I decided to fill anyway and it appears to have a good enough seal that it is not leaking, however I rushed to find a new pump and ordered an EK Kinetic D5. But now after looking more at EK's other pumps and a thread I came across someone mentions the DDC pumps are better for hard line, especially for lot's 90 deg angles because of increased head pressure. If I am considering going hard line have I made the wrong decision getting another D5? EK have a new VTX pump that they mention as suitable for small factor builds. Is this another type of DDC pump?

Asus Maximus XI Hero, 8700K 5.0Ghz, Custom loop: EKWB Velocity, X-RES D5, Rads: EK PE 360, Corsair XR5 280, EVGA RTX 2080 Ti FTW3 Ultra/EK Vector FTW3, Corsair Dominator Platinum RGB 32GB 3733Mhz, Samsung 850/860 Evo's, Seasonic Prime Ultra 1300W, Phanteks Eclipse P600S, Asus ROG Swift PG349Q 120hz 34"

In theory - Yes, DDC pumps will provide for a higher pressure value at a given flow point. However D5's will provide higher flow rates at a given pressure value for its PQ curve relationship..

In practice, it really is not worth worrying about for 99.9% of our builds as either of these pumps will provide ample flow rates for the majority of complex builds you ever see on this forum. If you really have a more complex build, - just use a dual pump top like I did.

Check out my single loop Deja Vu build which has a myriad of 90 deg fittings yet still achieves excellent flow rates (using 2 D5's).

I went with dual DD5 pumps and have not looked back. I have a failsafe on my Aquareot LT6 to shut down the PC if my flow rate drops below 55 L/ph.

Build: Z390 ACE
Core i9-9900K OC 5 GHz, MSI Z390 ACE Mobo, AMD Radeon VII GPU OC 2K MHz
Corsair Vengeance RGB 32GB 3200 RAM, Phanteks Enthoo Pro M SE.
EKWB Z390 ACE Monoblock, Bykski Radeon VII GPU w/b, 2x EKWB 140 Revo D5 Pump & Res.
Aquacomputer Aquaero 6 LT USB Fan-Controller, Quadro, Vision Touch and 'High Flow' Sensor.
(2x) HWL Black Ice Nemesis 280 GTS XFLOW and (1x) Alphacool XT45 X-Flow 280 radiators.
