50/34 has worked well for me. I mostly ride solo; if I was still doing fast group rides I can see the 52 or 53 big ring being nice to have. I still remember when a 28t was considered an easy climbing gear; now it's 30 or 32t on the low end of all my cassettes (40t for gravel). Really have no need for the 11t cog on any of my cassettes. Wish more cassettes started with a 12t so that I could have the 16t cog instead (I'm still on 10 speed).
