For me, it is a matter of repeat the same thing every turn (a save, easy to remember) or increment or decrement a value every turn (number of rounds elapsed). The second one is not really difficult, but requires an "extra operation".
Also, if more than one combatant is affected for different such effects, I find easier remember "this one needs a Will every turn and that one requires a Fortitude every turn" than "this one is on 3/5 and that one is 1/3".
