Unless you specifically need a lot of the dot net library (and in this case you can probably theoretically 'just' use a plugin for access) I would encourage you to try gdscript. I went from 5 years of unity pseudo-c# to it in about 2 weeks, and I globally just find it an equivalent if not better experience for the majority of the code base.
Honestly one of my current fears is that they focus on c# integration in place of improving gdscript support (the integrated ide is not specially comfy, and static typing support still lack some feature, collection wise in particular. but nothing really awfull).
