The underlying matters ~

If you're trying to leg into an option with a bid/ask 1.00/1.10 and .25/.35 you might get an easier fill by entering a .75 debit.

If you're going to try and leg in I'd say mid-day of a down day is best - then you have the chance of a "stick save day" allowing you to buy in low and sell your calls higher.

One other advantage of entering the whole spread is penny pricing. Take my hypothetical spread above you might not get filled at .75 but you might if you lower your price by a penny or two which you can't do if you're legging in.
