Should I buy a Synology or a UGREEN NAS?

The consensus across the reviewers we read is that it depends on priorities. Specialist communities consistently say Synology's DSM operating system and first-party apps (Photos, backup tools, mobile clients) are more polished and 'just work,' while UGREEN's NASync hardware offers far more CPU, RAM and 10GbE networking for the money. Multiple r/UgreenNASync threads summarize it as 'fantastic hardware, software needs to catch up.' Pick Synology if software ecosystem and reliability matter most; pick UGREEN if you want maximum performance per dollar and can live with younger software.
