I'll share here my positive opinion of GitExtensions (on Windows). It has really helped me use and better understand Git, while also helping me define and share workflows with my colleagues..

Other GUIs, like the ones embedded in VisualStudio, VSCode or Rider, try to sell skipping some cognitive steps for some operations as simplifying or speeding up dev flow. I find they are just offering extra (beyond what git itself offers) ways of shooting yourself in the foot.
