As a very long time power user (11 years, 140+ boards) I can say that Fusion Electronics still has a very long way to go to meet feature parity to Eagle desktop.
Sadly I don't think it will ever be as efficient or productive. Mostly in regards to how file management is handled.
It seems to me that the Fusion developers have never used a file browser before (sarcasm). The fact that we cannot drag and drop, Handle multiple files at a time, and quickly navigate a file tree makes handling files within Fusion a cumbersome trial in patience.
The way assets and libraries are handled makes it almost impossible to have a clean, fast workflow. In my Eagle desktop they are all contained in a (my custom) folder structure that I can quickly and easily manage in any file browser or Git tools. I never "upgraded" my libraries to managed as I want complete and flexible control over them. Sometimes I still manually edit the XML of my libraries in order to copy/add component variants.
Along the same lines your design files are locked in the terrible file browser without control over the structure. I use Eagle professionally to manage high volume product manufacturing and there are a ton more files I have to keep track of. I have scripts automatically export to a specific folder structure and that cannot be replicated in Fusion at all. Besides the design files there are PDF exports, BOMs, placement files, assembly drawings, changelogs, engineering change orders, design resources and datasheets, and gerbers all contained in a specific folder structure and tracked with Github.
The Fusion electronics file handling might be fine for the average hobby user with little documentation requirements, but for the professional the lack of flexibility is a huge issue that will keep me from ever being able to use it.
Also the control panel in Eagle makes it very easy to navigate and manage a large library, you know with a good expandable file tree.
Library management is quite bad since they started with the managed libraries. It was never well thought out and is still a mess. I've spent over 10 years building my 100% clean and custom libraries and not a single one is managed. I can still generate accurate 3D models with a workaround and still have all the flexibility of having local file management and Git version control.
Besides the file management (or lack thereof) there are a lot of other issues which impact productivity.
They added shortcuts which is a start, but it doesn't support the ASSIGN command so if you have a large set of shortcuts contained in a script file rebuilding those in the manual modal input dialogs will take a long time (also you can't edit them, only delete)
The latest update I decided to give it another try and it was very disappointing. The performance is still unusable. Opening one of my medium sized boards even mouse movement felt heavy and lagging. It seemed like it was rendering at 2 frames a second (High end Macbook i9, 64GB ram, 8600M graphics).
Just side by side with Eagle 9.6.2 it is VERY slow (and Eagle 9.6.2 is very slow compared to 8.7).
Fusion also has a lot of graphical bugs. On Mac if you use 2 displays a lot of times the browser or other menu elements show up on the other screens, or not at all. Move it to another desktop and the browser stays on the other one or doesn't show a lot. A lot of times I have to close and reopen Fusion to clear graphics bugs, which uses up time I could be spending on work.
Overall it just isn't a professional tool and sadly I don't think it ever will be.
Allowing local file/folder usage, fixing their terrible library management, and fixing their buggy/unstable release practices would go a long way though.
