EV6 vs Ioniq 5: Real range after 20k miles?

I’m torn between a used EV6 GT-Line and an Ioniq 5 Limited. Both are around the same price here, but I keep hearing different things about real-world range as they age. Anyone here with 20k+ miles on either? Do the 77.4/77.5 kWh packs hold up close to the WLTP numbers? Also, the EV6 feels sportier but the Ioniq has the better V2L and slightly softer ride. Reliability on the ICCU issue worries me for both, so has that actually been sorted? I’d also take a Model Y Long Range if the price drops, but the lack of physical buttons and harsher suspension put me off. What would you pick?
