I really loved the 2012-2015 line of MBPs. I didn't have a 15 inch, but the 13 inch one. It'll always be my favourite as it's the perfect balance between size/portability/power/style.
Agreed. My dream is a 13" with a quad-core CPU and TB3. With e-gpus progressing they way there are with TB3, my laptop is very close to replacing my desktop as well.
