Lowpoly modeling- cartoon car


Hello guys,
I’m modeling a Lowpoly cartoon car which caused a confusion for me that should I use chamfer in hard edges or not? or at least using it in the visible ones or not?
I have search a lot in the YouTube and the other websites but everywhere I found different results
Some say that we shouldn’t have any hard edges because we’re gonna have problems in baking process but some say it’s okay to have hard edges ,if we set the smoothing groups in a right way we won’t face problems.
I couldn’t figure out which is correct
I would be glad if you help me with this topic specially in case of cartoon car
Thank you so much
P.S. here I’ve used Chamfer in the car modeling
