I haven't had an issue with SD cards where Pis had reliable power. Where I used to live though we had frequent power cuts, of only a couple of seconds, a couple of times a day. SD card corruption was a major pain. Even in areas with more reliable power, for a 24/7 on device, occasional power outages have lead me to move away from Pis. Battery backups are, of course, an option, but increase the cost for a reliable and simple system.
