I've been using Aether for a couple of years. I almost went with MacLoggerDX but didn't see a way to automatically sync with LoTW. I guess I'm so used to Aether that I'll probably stick with it. The developer is pretty responsive, not I've had a lot of issues. Contest logging is tougher. N1MM has so many features that I've gotten used to and haven't found anything else that measures up. I run a Win 7 VM in VirtualBox for contesting. Keep checking out the Mac-based contest loggers but haven't seen enough to switch.
