I've been doing mostly solo for +25 years and now consider Rust + tailwindcss + htmx + Postgres the best overall. Before I could have said Django, then before Delphi, then before FoxPro.

One thing that is important in your calculations is how long-term is your outlook. What is nice to do in one week is a huge drag doing 2 years.

The more involved the logic or the more you are doing the project, the more paid to have a strict stack that solves the harder problem in the most correct way possible.

ie: js + nosql + schemaless and stuff like that, that sound simple will give negative productivity after a certain size and time on the codebase...
