There will be a turn and slip somewhere on any IFR certified panel.
A lot of people install a 2nd horizon in place of the T&S/TC because it is much more useful, and flying a precise rate 1 turn is anyway trivial with a horizon (usually 20-22 degrees at a typical IFR tourer cruise speed), and the only time one might be flying precise rate 1 turns is when doing timed turns which is an archaic procedure beloved in partial panel flying (I did most of my FAA IR on timed turns) which one would almost never do in reality, with a battery powered GPS available.
