I shared my Skyliner experience from last week here - Our MO/Resort Experience - Live Report 1/22-2/17 - #23 by Cgerres. The CBR station does get pretty backed up at times, and I believe they start running the Epcot line an hour before. If you’re able to be there early, the Skyliner might be fine. If you’re running late or it’s important to you to beat other people into the park, I personally would Uber.
If I was doing it, I would probably Skyliner to CBR sometime after 9:30 (when they people trying to get to HS have gotten through and the line is mostly gone) and then walk to Riviera and get in their Epcot line. I don’t love how the CBR line is HS and Epcot people together.
