What separates these tools is no longer the picture. It is the paperwork underneath it. One lets you run the output in a paid ad on the free tier, the next reserves that for a subscription, and a third keeps a licence to whatever you upload. Terms here change more often than price lists.
So each review covers what the tool does with a deck, a logo or a product shot, and also what you are allowed to walk away with: rights to the output, whether provenance data is written into the file, whether your uploads train the model, and who should skip it. Some links are affiliate links, always marked, and the verdict stays the same either way.

Usually yes, but it depends on the tool's terms and your plan. Free tiers often allow personal use only, or keep a licence to what you produce. Check two things every time: whether the output may run in paid advertising, and whether your uploads are used for training.
Trademark registration turns on whether the sign is distinctive, not on who drew it. The weaker point is copyright: for a purely machine-generated image it is not certain any arises, which matters the day you need to stop a copycat. Reworking the output by hand and keeping records helps.
You pay in credits or a monthly generation cap, so the real cost is the number of attempts before one image works. Cheaper tiers often mean lower resolution, a queue at busy times, or no commercial licence at all. Each review says what counts against the limit.
