Depends on growing habit.
And cages can make it hard to pick fruit.
Tall plants I'd stake.
And like North-East said (#3), if you put in a stake and then don't use it, no problem. But if you don't put in a stake and you should've, then you'll kick yourself.
Same kinda goes with cages, but if you don't need it, then it can be annoying picking fruit, like I said.
All in all, depends on growth. Good Luck!
