My personal reasons for buying a synology were ease of use, reliability and power usage.
I had previously played around with TrueNAS in a VM using an external USB HDD Enclosure for storage and I just wanted something reliable. With TrueNAS I often ran into issues with user permissions one way or another and the Synology software is incredibly easy to use and foolproof.
One question in regards to your noise comment: What drives are you running? I have a synology with 2 toshiba mg08 16tb drives and those things are unbearably loud when reading or writing. A lot of that obviously comes down to the drives themselves but I also kind of blame the plastic chassis for probably resonating with the noise and not being better at soundproofing.
