Should I Get Space Age?

Hello everyone! I have about 15 hours on factorio and I am LOVING it. I think I am willing to spend another 35 dollars on space age now that I know I like the game, and am wondering if I should go ahead and play through vanilla first or just restart and jump straight into space age? I don’t want to miss out on what vanilla has to offer if it is any different.

TL;DR : Should I play through vanilla first and then get space age or just jump into it?
