That would be the decision to make - does your toolkit support (or can
be made to support) the type and are you willing to choose a
sub-optimal database model because one or more applications happen to
do things differently?

IMO the daterange datatype is the best type you can choose for the
model; now you have to figure out and decide where any tradeoffs are
and if they are worth it given your specific circumstances.
