Visual Studio on Windows is good for F#, though it kind of needs the power tools plugin for F# to make it better. It's definitely not as awesome as the C# experience is, but still better than most!

https://www.visualstudio.com/vs/visual-studio-mac/ for mac is pretty good. It's less than visual studio for windows, but still ok. Easy to get started.

Visual Code, this seems a highly preferred option, and a lot of Fsharpers seem to use it, even on windows. The learning curve is a bit higher as it's not an out of the box experience. The trend is to combine it with FAKE, Packet and .NET Core (which I'm finding hard to keep track of).

I'm using VS for windows for F# product development at the moment.

On my Mac I use both visual studio for Mac for just mucking about, and visual code to play around with the toolsets the trendy kids keep advocating.
