In all seriousness, methods depend on the project. Sometimes an ethnographic study would be most appropriate, other times a generative study would yield more actionable findings. Over the course of an entire development cycle you’ll almost always use multiple research techniques so it’s hard to say which single practice works best.
On a broader sense, I am a proponent of user-driven, participatory design rather than an expert, designer-driven process. I don’t have enough experience to defend that position, it’s really just where my education took me.
