Nylon vs PETG Filament

So far i have only printed with PLA. The result is quite good but PLA is extremely hard (not elastic) and not to be used outside (e.g. UV, Temperature, etc.).
I say very interesting video on youtube for Nylon filament. But also promissing hints from PETG filament.
My question would be what are your experiences with Nylon and PETG printed on K8200?

What are the pro and cons?
Also shrink and printing reliability would be interesting?

Thanks for sharing your experience on this.
