Pros
Pro Has a free version
A free version, called SoftMaker FreeOffice, is available.
FreeOffice is a stripped down version of SoftMaker Office, with less features, templates and interface polish, but it still is feature-packed and with the same excellent import and export filters that enable opening/saving Microsoft Office formats faithfully.
Cons
Con Proprietary software
Although some versions/programs are free to download, they're all proprietary licenses utilizing a freeware model.
Con It's not Microsoft Office and it never will be
Use SoftMaker Office only if you want basic MS Office-like features. Once you delve deeper into the software the omissions become glaringly obvious.

Flagged Pros + Cons
Pro Closed source
It might be true that open source can help with bug fixes and new features but at the same time it makes your code visible and vunerable to anyone who is interested.
Out of Date Pros + Cons
Con At least in prior versions the free version lacked support for . docx files.
This is not really a con, as the company does have a right to try and make money.
