I'm amazed this is getting downvoted. I didn't expect LibreOffice's lack of quality to be a controversial fact. I though it was accepted as the status quo. After all, everyone agrees that Gimp is inferior to Photoshop, although it can be used fine in certain scenarios if you are willing to fight with it. LibreOffice is absolutely dreadful, much worse in comparison to Word than Gimp in comparison with Photoshop.
In GIMP, where are the layer groups? The nondestructive editing?
These are basic tools to a professional workflow.
And don't get me started on CMYK. You cannot do prepress without CMYK support; GIMP was going to get it Real Soon Now for the past ten years and it's still not there.
The reason for why no CMYK and why no non-destructive editing is that GEGL development took way longer than expected. Now that more and more of the GIMP core is converted to GEGL I am confident GIMP will eventually get these features.
GIMP is the story of what happens when you wait with new features until "the right solution" is completed. Not that I really blame them since they have very few developers.
If you're doing professional work, you should stump for a professional tool. Otherwise it's like complaining that your family car, though ideal for its purpose, is a load of crap because it can't take pallets.
Everyone doesn't agree that GIMP is "inferior" to Photoshop. They serve different markets. GIMP doesn't have as much manpower to put into the super high-end features, like tightly integrated RAW editing, but then people aren't paying 700 bucks per copy of GIMP either. GIMP does have features that Photoshop doesn't have (like a Python scripting interface) that makes it better for some use cases. For generic bitmap editing, either one works just fine, though GIMP is better for the casual user in most cases as it allows you to save your 700 bucks and put it toward something important.
LibreOffice is much the same, but I think the gap is actually much smaller. Microsoft Office does have some niche features that are not replicated by LibreOffice, and Microsoft has made their formats for annotations and other features that should be simple sufficiently complex to make import/export difficult, but LibreOffice in my experience is faster and has more of the features that I like and use (at least more accessible; apparently someone has said Office now includes direct PDF export, so that's nice). I use LibreOffice even if I'm using a computer with Microsoft Office installed. As with GIMP, in some specific cases, Word may be required, but in most cases LibreOffice works just fine and saves you hundreds of dollars.
The exception here is probably Calc v. Excel, because it seems true in my experience that Excel has many more features for power users than Calc.
