Ioniq 5 real range vs EV6: what are you seeing?

I’m looking at replacing my Model 3 and keep going back and forth between the Hyundai Ioniq 5 and Kia EV6. WLTP figures are one thing, but I want real motorway range at 70-75mph. Anyone here tracking actual consumption? Also, I’ve read about the Ioniq 5’s 12V battery issues – is that still a thing? The EV6 seems better equipped for similar money, but the Ioniq 5 has that longer warranty. Should I also be test-driving the Mustang Mach‑E? It’s discounted now, but reliability reports worry me. Curious what you all are seeing with recent builds before I put down a deposit.
