Deciding between a Mac and a PC depends largely on personal preferences, specific requirements, and budget. Here, we provide some general differences that typically emerge when the two are compared:

1. Operating System: This is a personal preference matter. Macs come with macOS, known for its sleek, user-friendly interface, and PCs come with Windows, known for flexibility and wide-ranging usage.

2. Hardware and Performance: Macs are often praised for powerful hardware and seamless performance. PCs, due to their vast range, have models that vary, from high-end to economical, with performance varying accordingly.

3. Design: In terms of aesthetics, Macs are often seen as more visually appealing with their sleek aluminium bodies. However, many companies, like Dell and HP, produce high-end PCs that rival Apple's design style.

4. Software: Macs are often preferred by creatives due to their robust pre-installed software suite (iWork, iMovie). PCs are generally catered towards businesses, and come installed with the Windows Office Suite.

5. Price: PCs range from budget to high-end prices, whereas Macs start at a higher price point and can be significantly more expensive.

6. Gaming: PCs are generally favored in the gaming community due to the wider variety of games available and the ability to upgrade hardware components.

7. Service and support: Apple's customer service is generally perceived as being superior to that of most PC manufacturers.

8. Compatibility: Windows PCs tend to be more compatible with more devices and systems compared to Macs, which can be more selective in their interoperability.

9. Security: Historically, Macs have been less prone to viruses and malware due to their closed ecosystem, but Windows 10 has made significant improvements in security.

10. Customization: PCs offer more options and flexibility when it comes to customization of the system and hardware.

In conclusion, both have their own strengths, and your choice will ultimately come down to your specific needs, tastes, and budget.

Yes, in general, Macs are often more expensive than their Windows-based counterparts. When you buy a Mac, you're paying for the Apple branding, the build quality, the great customer service, and the seamless integration with the Apple ecosystem. Macs are also often equipped with high-quality screens and powerful processors, which contribute to the higher price.

However, comparing on a like-for-like basis, a Windows PC with similar build quality, specs, and features as a Mac might also be expensive. Plus, Windows PCs are available across a broader price spectrum, from very cheap low-end models to highly powerful and expensive ones. This variability and choice in the Windows PC market make them seem generally less expensive than Macs, which have just a few models with less flexibility in configuration and a higher starting price point.

Therefore, it's essential to evaluate what you need in a computer, including the longevity of the device, technical support, system preference, and software requirements when determining whether the price difference is worth it for you.
