Absolutely. I've heard it said that the F4 was Nikon's best manual focus camera. I had two for a while, and (for what it's worth) I was never disappointed in its AF performance. Rock-solid design.
Its negatives are its thickness, weight, and all the damned interlocks on the thing. You have to learn its secret handshake in order to rewind the film. Would I buy one again when finances improve? Yew betcha.
