Here's my 2 cents...
Performance - Split tie for me. Both very good, Easton likely to be hotter a little quicker but fail comp much quicker too. We are seeing them fail comp with very few swings and we don't hit much else than 52/300s here. Crazy. The Worth can handle a bit more BP and use and maintain comp much better.
Feel - Totally different bats there. Sameish EL but that is where similarities end. I couldn't get with the FireFlex feel at all. Performance was obviously there, it just wasn't a feel I liked. My Dedonatis kept taking the day there > Bal FireFlex. (Harvey I've swung a lot and EL FireFlex too fwiw)
For a league that doesn't test? I would say FireFlex if you enjoy the feel. Hotter quicker (mind you not like Worth takes that much more work but...) People using them here smash the ball. More Eastons to be seen here again, the Utrips had just about died away cause they sucked with the 52s, not anymore. They gained back market share from the Miken/Worth dominance.
Conclusion - For me the Harvey would win on feel and longer term reliability. That being said, haven't seen cracked FireFlexes, just quick to fail compression. The GF doesn't love hers, and she still swing Green Helmer Flex or the 2016 Black Flex which both hers sit at pass line these days. It is a feel thing for her too, she says the FireFlex is hot but doesn't feel as nice as her older beloved 16 & 17 Flexes. I have to say, feel wise for me of the 3 I like the 16 Flex best. Just took 1000 cuts to get where a FireFlex is out of the wrapper LOL.
