I am generally pleased with the asymmetric ring on my 1X bike, but I'm really curious to hear the opinions of people who have never used one, which I'm sure we'll get plenty of.
I would genuinely say that the oval ring has helped my pedal stroke overall, but most notably on my round-ringed 2X bike-- much smoother now.
So I see it as a training tool. I don't think I'm climbing any faster or riding any faster. At least not to any degree directly related to the chainring.
