You can use things like Powersaves, you can back up the save digitally with the SD transfer tool just in case anything might go wrong (granted, you can't transfer it back, but you could then buy a digital copy), and you can't recover it if it's corrupted, which is more likely (especially with the 3DS' shit-tier SD card management - upgrading to a new SD card seems to be suicide for a lot of people, and even though it wasn't for me, sometimes mine doesn't read the SD card).
If you go digital, then yes, it's with you all the time, but if you're primarily playing Pokemon anyway, you may as well just leave it in the cartridge slot.
Plus, at least over here, the digital version actually costs MORE than the physical version (depending on where you buy the physical version, granted, but even then, it's still usually cheaper to go physical).
