Upgrading cars

I’m looking at upgrading vehicles soon. I’ve got a 9th gen si coupe. I really like the coupe body style, and love the manual. I was interested in the 10th gen coupe, but I’ve heard some mixed feelings. I love the drivers feel in the 9th gen, and I’m just wondering if I’m gonna lose that feeling in the newer generations. Other cars I’m thinking of 370z wrx sti.. let me know what yall think or if I should just keep it for the time being.
