Someday/maybe project vs context

I currently have both going, using the context for tasks/projects that fit into existing projects/folders I already use (for example, “paint the house” under household maintenance project). I also have a couple projects for things that don’t fit neatly: restaurants I might want to visit, concert tickets I like to check availability of, etc.

Am I doing this wrong? Do people tend to use one or another? And what would be the benefits/drawbacks of each method?
