Should I disable systemd-timesyncd if ntp is installed?

Is there any issue with running systemd-timesyncd and ntp on the same machine? I'm asking this because I have started using NTP on all servers but the systemd-timesyncd is running there as well. Should I disable it? Any issues with both running?
