The success/popularity/profitability of your projects doesn't depend on that. It doesn't matter. What does matter? Find product/market fit. Execute well (build a high quality implementation of your idea). Promote it well. That's 99% of success.

Creating a company (as in LLC or C-Corp or Inc.) is relatively expensive and requires non-trivial amounts of work just to maintain properly.
