Power Endurance is comparable to the Pro4 Endurance. Kyrlion is a down market tire that in my experience sucks, although the endurance version may be more durable than other kyrlions, the ride quality just never appealed to me.

For me, nothing else rolls like Pro4 Race tires. I preferred only Pro2 Race/Pro3 Race/Pro4 SC until changing over to tubeless. If I was buying regular tires they would def be Pro4 Race or Power Competition.
