The Hyundai Creta and Kia Seltos are mechanically identical, so your choice should boil down to which SUV's exterior and interior you prefer and your proximity to the brand's touchpoints.
It's worth noting, however, that the Seltos gets a heads-up display, which the Creta doesn't, while the Creta gets a 'boss mode' for the front passenger seat, which the Seltos misses out on.
