Helix does not aim to be a better vim / neovim. Thus, for example, there are officially no vim bindings and Helix follows the selection → action model. Helix is also a relatively new project.
When I first tried Helix, my main concern (that prevented me from getting too far into it) was not going from Vim to Helix, but the other way around. Vim (or sometimes vi) is a standard editor on almost any Linux machine, so if I am ever working on a server if a VM, I would need to know/use Vim keybinds. That made Vim a more useful tool for me to learn at the time, as I could use the skills both on my machine and anywhere else.
