What is the best groupset over the past 25 years (1998-2023) in your opinion?

Dura Ace 7800 for me and the missus. Her Trek 5500 and my 2007 Tarmac Pro both run it and it is flawless.

I actually prefer a nice track wheelset with a freewheel single cog. Great power transmission on the flats.

What i cant stand about the older silver shimano stuff like 7800 is that it looks like it has had worms the majority of times i lay eyes on one, its like the the alloy is getting eaten and little spiraled lines are left behind. The black plastic on the sides of the shifters made it look cheap too. Functionally then yes its top notch but there are several other groupsets that shift as well and stay looking nicer. 11s Chorus has been my staple. A - tier funtionality ultrashift without the price tag of DA/Record/RED. As for something that was a bargain..the latest Claris fitted to my winter frame has has all of the excellent ergonomics and funtionality of modern shimano groups and yet the complete set is cheaper than just a chainset from any of the current top contenders. I can live with 8 speeds on the commute.
