The main reliability issues seem to involve the REx engine, so personally I'd only buy the BEV. As for maintenance, replacing tires every 15-20k miles is the big cost. The battery is generally reliable.
If you're buying a 2014, make sure you get CCS fast charging. It was standard in 2015+. It makes a big difference those rare times when you need it. You can go from 10% to 65% in 12 minutes.
