Fair enough.
I have always had rather sporty vehicles so the suspension of mine (2021 3 competition) feels just fine. Sporty, rather hard, but not uncomfortable. Not floaty of course. Some people put a kw suspension for about 3k, which apparently makes it much better than comparable cars. I test drove one and didn't notice that much of a difference, so passed on the upgrade.
As for the materials, they are average or above in its price class. New VWs are notably worse. BMW are notably better but also 30% more expensive. Haven't been in an ioniq but non-electric Hyundai and kias are worse IMHO. The interior design is clearly very subjective, but the materials are just fine. Not a lot of hard plastics or anything like that, everything you touch is... fine.
