One can never be satisfied with the results. "There is no endgame", right?
1-2 hours is more than enough to get to work with autocompletion, syntax, filesystem explorer and a few more plugins for your convenience.
>coming from another IDE and trying to replicate something
This. Some people try to replicate IDEA or something like that. Obviously you can spend weeks trying to do this
Hell, configuring https://github.com/mfussenegger/nvim-dap + https://github.com/rcarriga/nvim-dap-ui can take a week alone I guess.
It is noteable that nvim-dap just provides support for debug adapters, if you are looking for nice UI, there are other plugins such as nvim-dap-ui [2].
In vim land, there is vimspector. I have not used vimspector myself, but from what I hear, it is slower than nvim-dap.
