There is and isn't. SRE is Google's more strictly defined DevOps, basically - after DevOps started to get slapped across everything (classic sysadmins, CI/CD tooling people, etc.), Google came out with something that basically defines, more narrowly, something very similar to the DevOps role (as originally intended), in a lot of detail.
There is a slight difference in focus though, because DevOps also focuses on the role's interactions with development, while SRE focused on the role itself and using metrics and data to be able to do the work required (SLOs, etc.).
I personally prefer the SRE term, because it's usually better understood and has a narrower meaning. DevOps can mean a lot more different things.
