Apple has zero to horrible support. There is no community. It's tech is a black box, it may is working 98% of the time but when it isn't you are fully on your own and have no actual way to do anything.

Not to mention that it looks and feels old, which most people likely don't care as it's still more modern than windows ever was since 95.

You will constantly pay the differences. In the 1 year or so I worked with a Mac I bought like 10 <$5 tools for things that would be a single command in Linux.

Depending on your hardware and what you do it will be slower, or slightly faster. If it's faster in anything it will likely run hot enough to cook some eggs on it.
