Used Ioniq 5 vs new Model Y — which makes more sense?

I'm cross-shopping a used 2022 Ioniq 5 SEL AWD (about 30k miles, mid-30s) against a new Model Y Long Range. On paper the Hyundai gives me ventilated seats, V2L and a quieter cabin, but I keep reading about ICCU failures and 12V headaches, plus the dealer charging situation near me is rough. The Tesla has the Supercharger network and better software, but the ride is firmer and insurance quotes came in higher. Owners: what's your real-world highway range been at 70-75 mph, and how bad has reliability actually been? Also curious whether an EV6 GT-Line is worth a look at similar money.
