Depends what you need. Even more so in a spreadsheet have I been told by my spouse (she is using advanced XL features a lot in her job). It also depends on what OS it's installed. I find it worse on macOS (much less well integrated) and real excellent on Linux.

I quite like using LO Writer as it's easy to set it up once and for all and have it behave exactly like I want it to be, including the very few extensions I use. Once configured, it's then very easy to backup all settings for quick re-installation or even to copy them onto another machine. It's also great to use different profiles for different pen names (ie having different dictionaries, rules, shortcuts,... depending the type of content one is working on) :)

I much prefer Writer's management of styles compared to MS Word too. I just think it's better... but it still is not perfect.

Depending your specific needs Writer may lack a few advanced stuff (stuff I'm confident 99% users will never use). I also don't like how keyboard shortcuts are managed as you can't really modify them freely but at least once can change them.

I will always make sure to install whatever the latest version is (the one installed with my distro always lags behind) as each update brings its fair share of improvements and bug corrections.

For writing, I use two different 'workspace': VSCodium (+Markdown and Hugo) for blogging, and LO Writer for anything longer. I consider both apps very reliable tools. I also like how I can easily tweak them to fit my needs and preferences.

I would not want to go back to using Word even though I never was a hater of Word. I started using Word in the 90s and I've been using it without any serious issue or drama up until I switched to Linux and LO a few years ago. Heck, I even managed to keep working with files I created back in the 90s without any difficulty, despite MSWord few format changes.
