Depends on what I'm building. Rails is fast to iterate on, a cobbled-together Go service is great for specific niches, JavaScript and TypeScript plus an ORM are good all-rounders that can help your team work across different parts of the stack and have interesting possibilities when it comes to sharing logic, and I'd probably build a toy project in Rust because Diesel is pretty interesting. The best answer is usually "whatever your company is already using", and unless there was a compelling reason I'd start with that.
