You guys have not been clear on the rest of the questions, as this forum has not been clear about it for years.

There are advantages. I have discussed these before. Does nobody remember?

What are the performance issues of all three?

What are the ease of use issues of all three?

What are the construction methods of all three?

I have answered these before. I'm not going to keep typing those answers.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
