What kind of trailer has more weight on your decision to buy a new indie game and why? Cinematic trailers or gameplay trailers?

I'm super curious about this because there are tons of different forms of trailers out there. Many indie games that come out release a mix of both kinds of trailers. Some would just focus on one type.

But I'm wondering which of them has more weight on deciding to buy a game.

If you've ran both kinds of trailers before, which of them were more effective for you?
