I'm not super familiar with tailwind plus, but I am familiar with MUI. MUIs paid offerings are open-core, you pay for support and a couple of extra features.

I'm not super familiar with tailwind plus, but I am familiar with MUI. MUIs paid offerings are open-core, you pay for support and a couple of extra features. Tailwind plus looks like paying for basic components (checkboxes, sidebars, buttons) and it doesn't even offer anything like DataGrid (free with mui).
