Mac (10000 programs)
Pros: Discreet. Nice GUI. Create multi-clipboards. Simple and advanced modes.
Cons: Some bugs.
Pros: High customisation; change anything from colours to blur effects. Screenshots can be exported to PNG or JPG format. Small price is highly preferable to hiring an expensive professional. Save your user settings as a template for later.
Cons: Only for mobile devices; not available for desktop. Some may prefer to pay for professional service if they don't have time or patience. Price only worth it if you're passionate about creating your own material. Takes some concentration to get the hang of each setting.
