I think the later ones are tuned to run on regular fuel and the knocking issue was in the initial 2016/2017 units before the software update.
If your budget allows and you’re fond of driving, then definitely opt for the turbo variant. The power delivery and torque is completely different to the oriel and I personally feel that oriel is a bit boring and laggy. Although the resale in the longer run would be better for oriel I guess.
