I had the use of an I30N for a couple of hours not long after they came out in 2018. They are great cars and much more performance orientated than a GTI. The speed, handling and exhaust noise really puts a smile on your face.
I just couldn't see myself living with one every day. I found the ride harsh and noisy, fuel consumption was poor and the interior of a Golf is a much nicer place to be.
It's probably an age thing as I'd love the I30 if I was still in my 20s.
