I know most people are partial to Shimano. I just went for Sram because options with the chainring tooth count I wanted was somewhat limited even in a standard crank arm size and I was limited to BB30, great bottom bracket, didn't want to change it.

I noticed that Shimano has it's own BCD design, so this could be an issue when swapping rings?

Those who are unbiased between the two or at least have experience with one or the other, which one did you find to be better overall?

I like that SRAM has more arm length options (167.5mm, 177.5mm...) and also more chainring combinations other than the standard ones like 34/50 or 36/52 .
