There are multiple types of semi-presidential systems in practice. Those where the Prime Minister is appointed by and accountable to the President (and not just by Parliament) are typically much closer to a pure presidential system in practice.

In France (source: I'm French) the President is typically extremely strong despite it being nominally a semi-presidential system, in some respects even stronger than his US counterpart. Also note that this depends a lot on practical details, like political customs — former President Nicolas Sarkozy famously publicly called his Prime Minister his "collaborator", for instance — and electoral timings. There was a reform in the early 00s to sync Presidential elections and Parliamentary elections, meaning that even though the Prime Minister is accountable to the Parliament, in practice the latter tends to be of the same majority as the President (whereas before, we had cases of Presidents and Primes being of opposing parties, which is known as 'cohabitation'), which gives him enormous power.
