2015 Maserati Ghibli SQ4 vs BMW i8, year 2016

Which car should I sell? I own both, but cannot keep two. One has to go. I love them both, Both are close to 60K miles. I cannot decide. Maserati has Ferarri engine ofcause and that throttle sound, like a god, seats also more comfortable, like a couch. And i8 has those doors, also faster than Ghibli from start, and design is slightly more cool than Ghibli, and has EV/ICE features the same time.

Which would you keep? Thanks!
