Susquehanna Polling and Research survey How competent is this polling group?

Very. One of the best based on their track record in 2016 and 2018. Pay attention to polls from Big Data Polls (Richard Baris), Trafalger, and Susquehanna. Ignore the rest.

Don't forget Democracy Democracy Institute/Sunday Express polls.
