crouch cancel > shine.
edit: z-cancelling is useful because you don't end up air dodging like a ****ing idiot if you ledgecancel an aerial and cancel with L or R. This can, alternatively, not happen by recognising that the situation will lead into a ledgecancelled aerial, which isn't difficult. tl;dr the difference is very minimal and I would just suggest using whichever feels more comfortable.
