There really is no best… Anything. Best is a personal opinion that you create on your own.
General responses to various questions:
What’s the best Linux® distro?
Please see http://www.distrowatch.com/ Which has a search feature, user comments, and pretty much everything you need to be able to start answering that question for yourself. Nobody in Linux.Chat can tell you what’s best, you need to find that for yourself and try various approaches/distros to see what suits your needs.
What’s the best text editor?
You have a choice. That’s the value of Linux®. vim, emacs, nano, pico, joe, jed, gedit, kedit, kwrite, code/vscode…. The list goes on. They each have their strengths and weaknesses, and the better question is to actually ask what types of features you are looking for in such an editor to better serve your purpose.
What’s the best media player?
Like the previous one, there’s plenty of choices, and no one answer will ever satisfy you besides what you’re looking for. Are you looking for Gnome, KDE, non-specific DE, console? Do you want streaming support? Do you want it to be able to stream? Be more specific and ask what you’re really looking for.
