Comcast/Xfinity router or use my own?

I just signed up for Xfinity/Comcast TV/Internet/Voice service. I know people that have always used their own router with the Comcast modem/router and others just use Comcast’s built in router. I’ve always used my own router with a DSL modem. Since the Comcast modem/router will be new to me, thought I’d ask if it’s preferred to use its router or continue using mine. I’m presuming range wouldn’t be an issue, but how is the Comcast user interface? For example are some user settings locked out, such as the ability to change or hide the SSID name? Any comments would be appreciated, Thanks in advance
