I don't actually notice much of a difference between the two, as the end result looks identical. If you use Vim and are switch to Neovim it's an extremely easy 1-minute process. I switched from Vim to Neovim. I can't say I found much of a difference, but the key points where Neovim could be better than just vim is that first, there are much more people maintaining Neovim compared to vim, which means fewer bugs and a modern code base. It also has a smaller code base which might result in a small speed improvement. Another thing is that it's basically just a fork of vim, so what harm can it do? ;)

Rust is probably a bad choice for starting out. It is a low level language where garbage collection is not done automatically, and has to get you thinking about all the technical aspects. It is statically typed and compiled, so it's very strict with how you code. I do love Rust though, it's a nice language. Golang is also compiled and statically typed, but it aims to be for quick development, which makes it a better choice for starting out.

Python though can be great for starting out and getting a hold on how to program. You don't need to worry about things such as types, garbage collection, or an overwhelming amount of data types. Since I'm a JavaScript fanboy I can't help but say another great popular choice to start is JavaScript 😁

I prefer functional programming because it produces less buggy code (thus I recommend F#), and is simply better to learn this paradigm earlier on in your coding career rather than later. It can also do most stuff C# can do, namely code with .NET core. If you're going to learn .NET then you should learn Node.js+Express first though before doing web development with C#/F#
