Shopping for a comfy soft top 4 seat convertible with a stick. Opinions?

I had a 2013 Mustang GT convertible, very comfortable, all the modern creature comforts, great fuel economy and plenty of power. I found it had far more room for me than the 2011 Camaro 2SS I had owned prior, though that car was a coupe. I'm 6 ft 7, and around 300 lbs. The biggest problem for me with the Camaro was the driver's door armrest location, my left knee was in constant contact with it, causing significant discomfort. Performance wise, the Camaro and Mustang were very similar, 426 HP for the Camaro, and 420 for the Mustang, and both were capable of respectable fuel economy, excellent handling for bone stock suspensions, and great braking ability. The Camaro's ride was somewhat more harsh, but not unbearable.
I have no experience with either of the other vehicles you are considering, so cannot offer opinion on them. Hope this helps some
