Would "table.insert(out, self)" be faster or slower than the above?

Slower, I'd think. It needs to make an external function call (not to mention the table lookup required to find table.insert, but that's quibbling), and table.insert is inherently more complex than the simple assignment. I could be wrong, though; certainly, I've seen 't[#t+1]=7' recommended as the Right Way of adding items to an array.
