Depends what you want out of it.
If you want an underdog story with a good presentation, no nonsense protag then it's worth watching. Lot of people liked the aesthetic and how Joe worked his way to greatness in a short period of time.
If you're looking for the next great sports narrative then it sucks. The competitions don't have enough build up for them to feel like they matter, the blows lack impact, the animation is average, the characters are one dimensional and barely explored. Gears become a wasted concept once you watch some guy off the street win fights without using them somehow.
It was designed to pay homage to Ashyta no Joe in a futuristic setting. But other than ripping off some scenes 1:1 it doesn't really do a good job of that.
