I remember my old Rollei T tlr had a Tessar lens, and when I bought the 'blad with its Planar, I noticed quite a difference using the very same standard film/soup combination.
The Tessar had a kind of glow to it, a plasticity that was very forgiving on human subjects, whereas the Planar cut like a knife. Pity that I hadn't kept the Rollei too, but trading up was essential on the budget.
