Susskind won't teach you things like friction, drag, or elasticity. But, he will teach you some of the most profound theoretical insights of modern physics.
Lewin won't teach you Euler-Lagrange Equations, or Noether's Theorem. But, he will teach you how to think about solving practical physics problems.
FLOP and Susskind's Theoretical Minimum are similar in that they both aim to teach an intuition of theoretical physics, rather than training one to do calculate the solutions of particular physics problems. So, they are similar in that respect.
The key difference that I noticed is that Feynman's intention is to explain nature, and he tends to avoid relying too heavily on the mathematics as part of that explanation.
Susskind's focus is on raw abstractions themselves, often independent of the physical phenomena that are being abstracted. His intent is to exaplain the mathematics, and to give you an intuition and appreciation for the beauty of those abstractions.
For example, Feynman shows you the Lorenz Transformations and says "this is the stuff that is needed to make Maxwell's Equations work out the same to a moving observer." On the other hand, Susskind starts with the notion that light has the same velocity in all reference frames, and uses this to derive the Lorenz Transformations algebraically.
I haven't read Penrose, so I can't comment on that.

They also have different sense of humour:
