Totally different models, the V5 is a 116610 modern Rolex with ceramic bezel, fat dot markers and blue lume/ rehaut engravings with a hefty, adjustable glide-lock clasp.
TC V6 is a 16610 classic Submariner with aluminium bezel, thin&elegant dot markers and green lume/ no engravings at all and with a light, gen-like, non-adjustable clasp (adjustable with extra tools).
Comfort: V5 is heavier and because it is adjustable possibly more comfortable
Quality & gen-like feel: Because of the better quality standards, movement and precision TC is incomparably better
Modded TC, normally it would have a Cyclops and a silver seconds hand
not a Noob V5 but the same watch-type for illustration purposes
