To me 52-36 & 11-25 is perfect for endurance (small ring) ans time trials (big ring)
While having enough top speed for sprints, and enough small gear for most climbs (not enough for walls with cobbles in Belgium tho :p)

That's pretty personal as it depends on power, power to weight, prefered cadences and what not.
When I last looked at it, it put me right between rings in a compact setup for some false flats I rode quite a bit where I live. I also used different wheels with different cassettes, and that somehow worked out better with standard gearing.
Long story short, use the gearing that suits your riding better, not the one that makes your bike lighter.

36:25T is plenty for cobbled Belgian walls, I did them on 39:25T man that was hard and slow.
I was using an old wheel with 9s on my 10s bike, worked surprisingly well without tuning.
But on the steepest section (28% I think) I hit 9 km/h minimum so I'm not sure if I would have made it without clips. But its fun!
Now I use 53-39 11-28 (10s) but the steps are way too big.
