They are both powerful. But the winner would always be the same ...Hal Jordan.
His willpower is just too powerful,and the GL ring operates on will power.
Even if you were to go to their uber-forms ....with Hal being Parallax and Kyle being Ion (basically both of them having all the powers of the GL energy), Hal would still win. Even though they are equally powerful Hal has more will power.
The rings and energies of Oa use will power.
Hal wins.
Everytime.
(Unless he decides not to win there is no stopping him).
