Whenever I had a lot of wires in a box and I knew there was no room for wire nuts, I used the push in connectors because that type connector took up a lot less room in a box. I'd come out of the connectors with pigtails for the wiring devices. Those connectors are also the fastest way to connect wires when changing a florescent ballast. ?(?)?

I have used a few like those in the last few years. There are also some
similar called something like walnuts. Those have a lever at each
position so they can be reused very easy.

I wish they had those out when I was working or atleast I wish I had
known about them. Used thousands of wire nuts replacing ballasts.
With around 6 to 8 per ballast you use a lot.
