I'm with @xstartxtodayx. Most of the latest and greatest is just rearranging the deck chairs. Great for marketing, but the ship is still the same. The viability of Pro's lineup is strong evidence if not proof of this. If the technology were clearly superior between 2005, 2015, and 2025 sticks, Pro's OG lineup would show it. The big inflection point remains packaging the T-Flex + composite blade as a unit in the Synergy. Since then, any changes have been more subtle than substantial.
To answer the main question, though I haven't tried a ton of different lines, the one stick did just work for me off the shelf a bit better than anything else I've had was RibCor2. It just had a combination of soft blade feel when puck handling with good pop on shots and, most importantly, perfect balance.
