The difference in the
procedures between Piper and Cessna are that the carbs in the Pipers are
placed so that they get warmed by the engine better, so it's not as big a
problem.

And it really only applies to early models of Cessna 172s.
Beginning in the '68 model year, the 172 used the same Lycoming
engines as Piper, with the carb mounted on the oil pan. For some
reason (probably liability), Cessna chose to keep their "always use
carb heat" instructions, even though the Lycoming engine is far less
susceptable to carb ice.

Looking at the big picture, it really doesn't matter much which
procedure you use. If you use carb heat for landing, you just have to
remember to shut it off if you go around or after you land.
