It depends on the scope and type of your project.
Construct 3 comes with the benefit of Scirra patching things up, pretty much on demand.
Just as an example. The NWjs plugin is outdated and has some broken actions because of changes by NWjs (3rd party). I have enough knowledge to workaround issues like that myself but if you don't. It might become an issue down the line.
Like with any unmaintained software. You'll have to deal with issues yourself.
