Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great starting point for kids
Scratch was developed specifically for kids ages 8 and up as an exciting way to introduce them to technology. It's designed to be easy to learn, but still provides good depth in computational thinking.
Pro Visual
Code is represented as visual building blocks that makes it easy to understand how a program is put together.

Pro Easy to learn
Scratch is designed to teach computational thinking rather than focus on specific syntax. It was designed specifically to be easy to learn for anyone over the age of 8.

Pro No need to be able to type

Pro Can be used to create games
Pro Highly structured
The language is highly structured. Therefore, it gives you the essentials of how to think like a programmer and teaches you good programming practices from early on, so you could write clean, working and readable code in the future.

Pro Free and open source
Inkscape is GPL-licensed and maintains public repositories.

Pro Opens lots of file types
Inkscape supports many common formats for import (including SVG, Photoshop and Illustrator) and its plugin architecture allows more to be added.
Pro Export to different file types
You can export and save your files for example as a "normal" svg, png, jpg, bmp etc. file.

Pro Cross-platform
Pre-built binaries are available for Windows, Mac and Linux. Inkscape can be built from source on additional platforms.
Pro Integrates well into a X11-System
Its uses the X11 icon theme and desktop theme(GTK).
Pro Dark Theme Support
The new 1.0 beta 2 version finally got support for dark theme which normally is only available for commercial software like Affinity Serif, Adobe Illustrator.
Pro Measurement Tool
This tool is extremely handy and I was not able to find it in any other vector graphics programs out there.
Pro Live Path Effects
Extremely powerful menu that offers more than 30 powerful Live Path Effects to apply to your paths vastly enhancing the application functionality.
Pro It can do anything
A very powerful software that can do pretty match anything!
Pro Guides, Grids, and Canvas Rotation
Extremely handy features when building complex graphics using Inkscape.
Pro Interface is available in 29 languages
Basque, British English, Brazilian, Portuguese, Catalan, Croatian, Czech, Dutch, Finnish, French, German, Greek, Hindi, Hungarian, Icelandic, Indonesian, Italian, Korean, Latvian, Norwegian (Bokmål), Polish, Romanian, Russian, Slovak, Spanish, Swedish, Turkish, Ukrainian, Urdu, Swedish.
Pro It's really easy and fun
You can edit and create vector graphics with Inkscape.
Cons
Con Does not teach you programming
Learning Scratch might help you if you have high difficulty with logical thinking. However, starting with a proper programming language, especially an easy one, will give you the benefits of starting with something like Scratch and everything else.
Con For kids, so don't even mention it in a job interview: it makes you look like a noob.
Con Won't get you a job
Scratch is not a language used in the workplace. Instead it teaches computational thinking, helping to create a foundation to aid in learning other languages.
Con Strange OOP
Scratch has a very strange implementation of OOP that is sprite based, and will become very confusing when you move to other languages.

Con Very slow startup on some systems
Depending on factors like how many fonts you have installed, Inkscape can take upwards of 30 seconds to launch.
Con Uses its own SVG-format by default
Inkscape might use SVG as its default format, however this SVG's contains some additional SodiPodi/Inkscape additions that can be troublesome if you want to import the SVG into some other application.
Con Based on the GTK widget toolkit
Software is based on GTK, so it might not integrate well in non-GTK environments. It also requires many dependencies on those non-GTK desktops. It also adds dependencies to GTK-environments since it is written in C++ which requires the gtkmm wrapper/interface.
Con Incompatible with previous versions
Sometimes backward compatibility breaks. For example, pre 0.92 SVGs are incompatible with later releases (due different default resolutions).
Con Crashes very often
Inkscape encountered an internal error and will close now - is one of its standard messages.
Con Mac version does not look as polished as its versions for Windows/Linux version for the 0.92.x version
It seems that Inkscape 1.0 beta 2 for Mac got some needed attention and it looks a lot better with dark theme support. native DMG installer and they got rid of X11 which is great.
Con Since 0.91 the gradient editor is gone
It is now only possible to edit a gradient on screen. but you can't set a stop to a specific percentage anymore.
Con Buggy
Application is often buggy so it happens from time to time that the popup / right-click menu won't close and stays open. It crashes also sometimes randomly. This makes it almost unusable for productive / business use.
Con Y-axis inverted
0,0 coordinates begin in lower left corner, not upper left corner as SVG standards define in Inkscape 0.92.x.
It seems this is now fixed in the 1.0 beta 2 version of the program.
Con 1.0 is sluggish
Inkscape 1.0 uses GTK 3 which is sluggish and slow for low spec systems( eg. ARM, Celeron, Pentium, Core-i3, Ryzen 3 or Athlon ) compared to previous versions.
Con No support for large printing machine system
No support for large printing machine environment, except exporting the resulting artwork to PDF.
Con Under GNU GPL
It is released under GNU GPL which one of the restricted open source license.
Con Limited work with ICC CMYK color scheme
Support for ICC color profiles only in SVG files.
