What I don't understand is why a 1.3KW heater would be better than a

there's no option of a 1.3KW cycle.


It *might* be better, if. e.g. the 1.3kW can operate at 100% duty cycle,
but the 2kW keeps hitting its overtemp stat and operates on less than a
65% duty cycle.

So how would you know this before buying the heater ?
What would you expect if you brought a 2KW oil filled radaitor ?
