This might sound hyperbolic but as a .NET developer JetBrains Rider is a real joy to use IMHO. I think being paired with an M1 Mac is probably part of what makes the experience great for me.

That IDE/hardware combo beats anything I've ever developed on in my career. By a long way.

Shameless plug but I mention it and a few of my other favourite software tools here:

The other "sparks joy" software I use regularly are Sketch - which after a lifetime of using Adobe products felt like a breath of fresh air when I switched to it - and Proxyman which is hands down the best HTTP interception/proxy software I've used on the Mac (and iOS).
