Immeasurable is not a direct synonym.

Infinite means that it is endless without any limit (and makes it clear), immeasurable additionally means that it cannot be measured and that it is unknown if his power has a limit.

Infinite just makes it clear that he has NO limit, but it was never stated in the series that he has no limit, it is just "seemingly" limitless and it is unknown if he actually has one or not.
