Most modern groups function just fine. You lose weight and gain a bit smoother action by moving up the line. Also the highest groups often are the most specific, unable to mix and match with other components. There's definitely a sweet spot in each manufacturer's line that gives the best performance and durability for the money, and it's not at the top.
