I wear a non perf leather jacket year round pretty much, mostly because I just like the aesthetic way more. But that's just me.

During the summer months, it doesn't really get so uncomfortable to the point where it made me want to buy a second jacket. Of course it did get toasty at times, but just leaving the front unzipped gave me enough airflow to not have it really bother me that much.

I would think that perf does give you a bit better air flow. It really just comes down to personal preference
