Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GIMP

GPLv3 licence requires derivative works to be open-source and freely distributed
Community-driven development with no commercial support tier
No native CMYK support for professional print workflows
Ecosystem depends on community plugins and scripts for advanced features

Sigil

It produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.
Meaningful use requires reading and writing HTML and CSS, which puts it out of reach of most authors who simply want a finished file.
There is no cloud storage, sync or collaboration, so the book exists as a file on one machine and version control is whatever you set up yourself.
Development depends on a small number of volunteer maintainers, so release timing and platform builds follow their availability rather than a roadmap, and a lapse in maintenance would leave no obvious successor.
It provides no distribution, no retailer connection and no Kindle-native output, so it sits in the middle of a workflow that other tools have to complete on both sides.

Answered from the vendors’ own pages

GIMP: How much does GIMP cost?

GIMP is completely free to use and distribute. The software is released under the GNU General Public License v3 (GPLv3), an open-source license that guarantees freedom to use, modify, and distribute.

Source

Sigil: Can I write my book in Sigil?

You can, but you should not. It is an EPUB editor, not a word processor, and writing long-form prose in it is unpleasant. Write elsewhere, import, then finish in Sigil.

GIMP: Can I modify and distribute GIMP?

Yes, GIMP's source code is available for modification and redistribution according to the terms of the GPLv3 license.

Source

Sigil: Does it make Kindle files?

Not natively. Produce a valid EPUB in Sigil and let Amazon convert it, or use a separate conversion tool for other Kindle formats.

Sigil: Is it safe to rely on a volunteer project for commercial work?

The files it produces are standard EPUB, so nothing is locked in. The risk is that maintenance stops, not that your books become unreadable.
