Rust/Neovim setup?

Since I typically use VSCode but always with VIM bindings I thought I might give Neovim a try to see if it works any better for me.

I just wondered if anyone could explain their preferred setups because the amount of choices even for the most minimal setup is somewhat confusing.

So far I'm using only rust-tools, lsp, lspconfig and telescope. This gets me in line errors/warnings, go to definition/impl, type information and almost everything I need but the default autocomplete doesn't feel as reliable as in vscode and when passing params to functions I don't automatically get the function signature as a popup like in vscode.

Any tips on how to fix my setup or suggestions on things I'm missing would be great. I'd also consider premade configs if there are any aimed at Rust dev.

Update: I think what I might be missing is compe but I'm not sure how that differs from the built in completion
