I'd say, it's innovativeness. Whether the product can improve something I'm doing better than others? Create videos, organize stuff, obtain experiences, generate something, protect my data, communicate...... and so on.
That's what influences my opinion most.
@arthen_factory ok, the most important factor I would consider is the product’s VALUE PROPOSITION; how well it meets a need for its target audience , understanding the unique benefits it offers compared to competitors , if the value proposition is strong, other factors can be optimized overtime
@oyinkansola_robiat, in my opinion the over user experience interacting with the product. So this includes whether the product provides the intended features as well. But the point is that even if a product provides the features but if it is not easy to interact with it , it is not good.
