Need suggestion on finalizing car - Seltos -Taigun -Elevate

Hi all, I’m relatively new to the automatic car world and after lot of YT videos and test drives i have narrowed down on Seltos IVT HTK O (Petrol NA) variant

The ride felt smooth and features sufficient for my ise case of mostly highway drives and less city driving with spacious cabin and boot along with decent interior

But as i am reading reviews and watching more videos , thoughts come across my mind if i should consider Taigun for its power? I am not sure how different is 1L TSI engine from my current Altroz Petrol NA car , both which have 3 cyl engines. I don’t want to run into same 3cyl engine issues ( if at all Taigun can have same issue which i am not sure) does it matter? Hopefully it is better?

Mu driving preference is definitely not rash or one who would want raw performance , but i need decent power in hills and ghats with 4 people and luggage for trips

What is the best option and suggestions you would give?
