As I was also considering that, tried many options.
First was Daily spending, but noticed facebook spending budget overnight and not really getting resuls.
The best option for me was to launch Lifetime budget, 30 days, from 6am do 9pm.
Also tried 4pm to 9pm, facebook couldnt spend budget in that time frame.
Also tried 6am do 12pm, facebook spent budget and I managed to get 100% results that I would get in whole day of work, it was little bit more expensive but I was doing whole days work in just 6h.
Try different things for your niche, see what works for you and your audience.
