Need a recommendation

Hi all, I've only just finished my motorcycle course and am looking to purchase my first motorcycle ever. I would definitely be purchasing a 2nd hand.

I have narrowed my choices down to either 2017 Ninja 300 (has 17,000 in the odo) and is going for $5,500 or the 2017 Duke 390 (has 3,000 in the odo) for $6,000 / 2021 Duke 390 (has 8,000 in the odo) for $6,000. With research, I've learnt that the 2017 and 2021 Duke 390 is almost the same.

Not having ridden a motorcycle before, I'm not sure what style would suit me better, but I prefer the look of the Ninja much better. I would mostly be using it for commute to work (20 kms each way - around 2 days a week) and some weekend rides here and there.

Any input would be appreciated.
