I’d personally look at job trends, particularly remote jobs. Which one has more job listings, and does one have a better growth trajectory than the other? That’s how I’d inform the decision were I in your shoes.
Do you have any resources for looking at job trends for a specific language?
I've been doing a bit of that although I'm not quite sure if I'm looking in the right places to make an accurate assessment of that. Rust seems to be winning out by this metric though.
