Interesting that they added the blue glowing stripes to the Discovery. For me that was always a TNG-era marker. Until ENT. But then Abrams-Trek got rid of them again. Now they're here again. For the record: I can live with them. But I never was a fan in the first place - it's my least favourite design aspect of the Ent-D.
The Shenzhou looks like a finished, polished Star Trek design. The Discovery is still a mess. A mix of different styles, clashing aesthetics (brutalism vs. elegance), last-minute fixes and some designers finally being able to cram their pet peeves into a pre-existing design (like John Eaves and his cut-outs)
