Have you heard about WPS Office.

Meh .... I prefer Open Office. I'm happy with it and don't feel like changing now.

I recently started using MS Office 2013 and it's really nice. I used to use Open Office and it does the job perfectly fine.

I have it on linux, I don't like it's word processing, but it's presentation IMHO is better than Open/Libre office's slideshow/impress.

I liked using Softmaker Office because it's more lightweight than other office suites. There's a free version, FreeOffice.

If you look at the "products" tab, you'll see the "office" things come as a free version AND a paid "pro" version with unlocked features (more rows in spreadsheets, and so on). OpenOffice or LibreOffice are really free products and don't come with pay-to-unlock features.
TL;DR: not for me :)

I've used MS Office (from 2003 to 2013), OpenOffice and LibreOffice. Every one of them has its own benefits. Might try this free version jst to compare but would hardly consider a switch as I am comfortable with LibreOffice for now (and the occasional MS Office).

I use MS Office 2013 on my desktop, it is great and faster than Libre/Open Office. Tried ONLYOFFICE recently, looks promising but lacks lot of functions from MS Office.

I am using WPS Office and pretty content with it in spite of it not having my local language version

WPS office is awesome. "I can't believe it's not Microsoft Office".
