Oh yeah. The smoke helmet is definitely the worst among them. As for airsoft, it's ok as a training tool, especially if there is a concern for affordability, since it can help train one's reaction to a threat and their individual skills like drawing or reloading. However, it's much less accurate than simunition and doesn't provide solid shot placement information or confirmation unless you get hit in softer regions like skin or a t shirt. Plus, it's not that loud, so it doesn't provide immersion.
