Non veni pacem mittere, sed gladium.
The Saturn V was in a class by itself. Technology has come a long way since then, but the Falcon Heavy won't send a crew to the Moon and return them safely to Earth. The Saturn V did that over and over.
As much as I would like to compare the falcon heavy and the Saturn V, the Falcon heavy is really only a direct competitor to the Delta IV heavy for payloads to geostationary locations. With the Falcon heavy only having better performance to low earth orbit. In other words, it's a numbers game and the Falcon heavy is a much smaller and less capable rocket when compared to the Saturn V.
Falcon Heavy "won't send a crew to the Moon"? Are you CRAZY or JUST OLD?!
Anon: "Falcon Heavy "won't send a crew to the Moon"? Are you CRAZY or JUST OLD?!" Well, from a practical standpoint, the FH can loft a small manned capsule and get it around the moon. Nobody thinks it can lift enough mass to the moon's surface to replicate past missions.
