Good problem to have.
All depends on your final preference.
If you want a bigger car, more room, do more long road trips, I would say Oshan X7 with the radar ie future sense. Facelift is much better in terms of interior color. More dealerships countrywide.
H6 has some more features and might give a little bit more premium feel from inside. Not as big as Oshan. Less power than Oshan but it’s not underpowered, just that Oshan is a beast in terms of power. Bit better resale.
Up to you to decide.
For final decision sit inside both and do test drive of both from dealers.
