Seekins PH3 or Element M3. I have the latter in 6CM and it is incredibly accurate and a massive upgrade over my PH2 (also in 6CM and also incredibly accurate) in terms of bolt feel and versatility. Their new quick fit barrel and bolt head system works well! I’m rotating between a 6CM barrel for hunting and a 22 arc barrel for training (the 22 Arc barrel and bolt head cost me $700 bucks from EuroOptic).
I like my Tikkas but they just don’t match the performance of my Seekins out of the box. If you are talking easy button, it’s Seekins.
Buying a Tikka and changing out the barrel and stock is fine but certainly not the easy button and you’ll be waiting on parts for months in most cases.
