APC is better for return loss, but from what I see no commonly used fiber systems care that much about return loss (only old analog-over-fiber systems?)
I had standardized our company on SC/UPC since the connector worked everywhere - patch panels (not too tight like the tiny LC), SFPs (we use BiDi so only need one connector, can fit an SC), NIDs. Unfortunately, many 10Gbit BiDi SFPs are only available easily in LC/UPC. And some GPON ONU CPEs are SC/APC. We have adapters for those cases but it's annoying to move away from the standard.
