I just quickly checked Nasser Abassi 12000.org to see if he's updated it for Maple 2017. In some areas he has. I thought I would check one of the integrals that failed for Maple in his tests. In the Computer Algegbra independent integration tests Maple failed to solve 11.68% of the 3407 integrals in his test while Mathematica only failed 0.88%. For Maple that seemed quite high, so it is perhaps his method of solving for Maple and perhaps he's more adept with Mathematica.
Here is one of the failed integrals and the single line code he used to solve it.
int((5*x^2+3*(x+exp(x))^(1/3)+exp(x)*(2*x^2+3*x))/x/(x+exp(x))^(1/3),x) # of course because it failed it just spits back the integral.
Can maple solve it?
The answer is supposed to be
