As of November 2020, Pioneer 10 is the 2nd most distant spacecraft from the Sun and Voyager 2 is the 3rd.
However Voyager 2's heliocentric velocity is significantly higher than Pioneer 10 and it seems destined to overtake it sooner rather than later.
When will that date come?
There is useful current data at Heavens Above. The relevant bit is
Voyager 2 is currently (Nov 2020) 125.4 AU from the Sun travelling at 3.231 AU/year, and Pioneer 10 at 127.2 AU and 2.512 AU/yr.
So we expect them to change places in the list in $$\frac{127.2-125.4}{3.231 - 2.512} = 2.50\quad\mathrm{ years}$$ so roughly May 2023.
