The OP almost had it with attempting to use PolynomialForm[]. All that was missing is the use of an appropriate setting:
PolynomialForm[a x^2 + b x + c + x^3 /. x -> (x - a/3),
TraditionalOrder -> True]
(x - a/3)^3 + a (x - a/3)^2 + b (x - a/3) + c
As is usual with *Form[] functions, this is only suitable for display/pretty ...

The trick is to use the Inactivate function to prevent Mathematica to apply the powers.
Inactivate[{2^2, 3^3, 4^2}, Power]
Then use SortBy function to compare the Active forms of the elements.
SortBy[Inactivate[{2^2, 3^3, 4^2}, Power], Activate]
Result:
{2^2,4^2,3^3}
