Is an old cast iron tub worth keeping?

Very often yes. If the shell is sound and the problem is the finish, old cast iron is often stronger and better than low-end new tubs.

Is cast iron better for enamel or liquid acrylic?

Both are possible. The choice depends on the surface condition, budget and the finish thickness and durability you want.

Because removal and carrying are usually much heavier, noisier and more expensive than restoring the surface.
