HELP ME OUT GUYS!!

[u/Professional-Fact-27]

Test rode the Tracker 400, KTM ADV 390(350cc) and the guerilla 450 today.

Please help me decide which one to buy( I liked the guerilla so much in the second gear I ended up booking it)
I have a few months waiting to reconsider my decision.
Obviously I liked the guerilla 450 over these two, but now I am in a delusion if I did the right purchase

I am a 18 year old male having fair enough riding experience of riding the yamaha MT 15 and the RE Himi Scram 411 belonging to my father. I would be riding bije daily 25-30 kms in Peak Mumbai traffic and also weekend fun rides

1. The GRR 450 is the most expensive out of these three, and also would require the most maintaining imo.
   
2. I need a city traffic commuter as that is also a purpose that the bike would have to serve.
   
3. Would the guerilla be very expensive and attention seeking to me in terms of fuel and servicing?

Pls give out yall’s opinions as it would help me out a lot and also feel free to suggest me any other bike other than these three.
Thank you in advance 🙏
