In 2018, does SSR still provide an advantage over CSR for: (1) SEO, (2) performance?

I have read a number of articles singing praises for one or the other. SEO and performance are the two greatest weapons that SSR seems to wield over CSR. However it seems that in 2018 most search providers have crawlers capable of parsing JS and some async calls (up to 10s for Google). And with frameworks like Preact being tiny, especially when gzipped, I don't really buy the performance argument either. Has anyone come across a definitive, recent writeup that compares the SEO and rendering performance of SSR and CSR?
