I have been round to oval chainring for years and then back to round. I also went from 170 to 165mm cranks on the MTB. While I could feel a difference I wouldnt say either was “better” necessarily, the body just adapts and after 60 mins or so I couldnt really notice anything was different.

I went bigger by 2t going from 175 to 165 since you’ll have less leverage (if that makes sense)

I would have thought it would have been a reduction in chainring size.
I’m not changing my front ring. I’m not missing any gearing just I’ve not quite adapted to the subtle difference for musucling over repeated obstacles when at a low speed on a climb.

Yeah I’ve had a similar experience to you.
I just cant ever be 100% sure if it’s just lack of fitness, or if there’s actually a measurable difference.
