At least for our use case (reading slices from varyingly sized rows from 10-100k composite columns with counters and hundreds of writes/second) LCS has a nice ~75% lower read latency than Size Tiered. And compactions don't stop the world anymore. Repairs do easily trigger a few hundred compactions though, but it's not that bad.
