9, 10, 11 speed system's future - CUES or Old Standard?

[VonPG]

Now Shimano release CUES drop bar system. Which is not compatible with old 9-11 cassette, rd, fd, and shifter.
Other brands still make 9-11 speed groupset.
Microshift - old standard.But new Advent, Advent X and Sword rear derailleur pull ratio is similar to cues.
Sunrace - old standard and CUES both. RS/RX/R9/MS/M9 for old standard, UX/US/U9 for CUES.
Sensah/Ltwoo Mechanical - old standard.
Sensah/Ltwoo/Magene/Wheeltop Electronic Groupset - Due to their rear derailleur can adjust cog pitch, they are compatible both.
TRP/TEKTRO - old standard(Not sure TRP HYWIRE)

Choose CUES
Bad - Heavy Weight, Delay shifting when upshift(big cog to small cog), Less Comptibility to Old Standard, Less choice for gear ratio.
Good - Durability, Encourages Strong Pedaling to Change Gears.

Choose Old Standard
Bad - Less durable compare to CUES.
Good - Compatiblity, Less weight for cassette.

If you want to build a new bike, which system will you choose in the future? CUES or Old Standard?

I migrated away from 9,10, and 11 speed systems 3 years ago and all of my bikes I ride are upgraded to 12 speed. (1X12 and 2X12)   The only Scumano parts I use these days are their Mircoshift 148mm and 157 rear hubs, and a couple 12 speed 8100 series cassettes.   
2 of my older road bikes have Microshift ARSIS components on them.

I went down the evil path of adopting Wheeltop EDS components.   So far I am happy despite the problems I have had with some of Wheeltop's reliability.

I'm still mixing sensah new and sram old components I have. Once all my old shifters are cooked I'll probably try Microshift Sword black.

If I was running mechanical, the only thing that would interest me is running 11 speed CUES drop bar shifters on an 11 speed wide range CUES RD. I'd be fine using an XD or Micro Spline 10-XX cassette and whatever lightweight 1x crankset setup.

It is compatible with any 11 speed chain and cassette. Source: I am running CUES U6000 with Sunshine cassette and KMC X-11 chain. Shifts so good.

You can pry my old 11s XT and sunrace out of my cold dead hands!
