Yet Vader knew that if he had one misstep, Obi would kill him.

Except, Obi has an answer for Tiin's speed(moving with speed that surprises Vader) and for Tiin's strength(Matching Vader blow for blow)
I hardly see Obi having anything more than a small to medium percentage of difficulty against Tiin at best. And that's mostly due to Tiin being younger and Obi's lack of TK showings at that age.
