Saturn 1B was huge and it dwarfed the Titan 3C, which was a large rocket in its
own right.

Here's a picture I found on Reddit showing various crewed launch
vehicles to scale:

Falcon 9 really is a beast. It doesn't look like much compared to the
Saturn IB, but to quote Han Solo: "She may not look like much, but
she's got it where it counts, kid."

But when you compare Saturn V to SLS 1A and SLS 1B (remains to be seen
if the EUS for 1B will ever be built), SLS falls short in the
performance department. NASA keeps boasting that SLS is "more
powerful" than Saturn V, but that's only liftoff thrust. The fact is
those SRBs do have high thrust, but their casings are *heavy* and their
ISP is terrible, leading to worse performance compared to something like
the Saturn V's first stage (LOX/kerosene like Falcon 9).

FWIW, Wikipedia has these figures, whereby payload to LEO is slightly
higher for SLS Block 2.

The Space Launch System (SLS) is a US super heavy-lift expendable launch
vehicle. Payload to LEO. Block 1: 95 t (93 long tons; 105 short tons);
Block 2: 130 t (130 long tons; 140 short tons)

Fully fueled, the Saturn V weighed 6.5 million pounds (2,950,000 kg) and
had a low Earth orbit payload capacity originally estimated at 261,000
pounds (118,000 kg), but was designed to send at least 90,000 pounds
(41,000 kg) to the Moon.
