Always loved it. Right now the Umbrel has a larger variety of software, but Embassy is far more focused on security. I think with enough time the app ecosystem with Embassy will open up, and the Pro is way more powerful obviously, but the app selection is larger and can do a larger variety of things right now on Umbrel.
So it's whatever you want to prioritize really & what your timeline is. I have no problem personally making the investment in the more powerful Embassy with the expectation of what I know it will be able to do later this year and next. I don't think you'll regret it if you do.
