You'll have to forgive me if I disagree.
Vector's spartan, or simplistic design works better for a TOS-era drydock.
Madman's Prime Alternative looks more like a Phase II-era and above to me.
I totally agree. Vektor´s drydock has all the recognizable elements from TOS.
Madman's drydock is an excellent concept, but fits in the "Prime alternative Universe" or as a pre-Phase II, but surely not in TOS-era.
