Your choice has to do with your prognosis for the underlying. If it's trading sideways, you'd be looking more at a calendar spread or iron condor. If it's uptrending you'd be looking at a put credit spread, downtrending it'd be a call credit spread.
Calendar spreads, iron condors and credit spreads take advantage of theta to make money. Your choice depends on where you think the underlying is going.
There's no free lunch with option plays. You have to bet on underlying direction (up, down, or sideways) and take the consequences if you're wrong.
