I'm currently comparing E6 and Awesome Golf algorithms through testing and hope to share video results this week. While the Garmin Golf app is shorter, I suspect these other options will be more accurate on default settings.
Yeah, the R10 is still a strong contender for the best budget option, as it avoids any yearly subscription fees. When considering where to purchase, Dick's Sporting Goods and Golf Galaxy offer a generous 90-day return/exchange window, allowing you ample time to ensure you're satisfied with it.
