Helix doesn't have tabs or folding, I find it really hard to use an editor without those features. The preconfigured LSP stuff is nice, but after you set it up in vim you usually don't have to mess with it unless you want too.
As with most engineering tools, I think using the word "better" is not necessarily correct. It's a matter of tradeoffs.
For me, I was fed up maintaining code to run my neovim setup the way I want, so I was looking for a configuration distribution or... something else.
Helix was the dead simplicity I was looking for. It has its own warts and drawbacks, but the tradeoffs are well worth it in my experience. I absolutely love Helix!
But if you want your editor to work exactly the way you want and having maximum flexibility is more important, you will not like Helix, which is extremely opinionated and has 95% of what you want in a modern text editor. The other 5% may be a deal breaker for you.
Not that I want to muck around with plugins all day, but having the ability to add a few helper plugins to ease certain tasks is a godsend in terminal editors.
Especially if you really dislike certain defaults packaged with the editor.
