Redis vs Memcached in 2025: is there any reason to choose Memcached?

i'm having a debate with a colleague about redis vs memcached in 2025. my colleague is a big proponent of memcached for 'pure caching' scenarios where you just need simple get/set operations and don't care about persistence or advanced data structures. they argue it's simpler, faster for its specific use case, and has less overhead. i, on the other hand, almost always reach for redis because of its rich data structures (lists, sets, hashes), pub/sub capabilities, and optional persistence, even for simple caching. the operational overhead difference feels negligible these days, and redis just gives you so much more flexibility for future needs. is there still a valid reason to choose memcached over redis for new projects in a modern distributed system, assuming you only need basic caching? i'm curious about real-world scenarios where memcached still shines.
