I've currently got three apple laptops (15-inch Macbook Pro (2013), Macbook (2016) and new Macbook air (2018). I tens to buy the top-end variants. They are (very) expensive, but I would not use a Windows machine.
Why?
1. Operating system
1a. Where Windows forces you to do things in a certain way, MacOS does not.
1b. MacOS is based on a Unix variant, which is intrinsically more secure; Windows is based on a registry that opens the machine up to security threats
1c. MacOS forces developers to use consistent keystrokes across applications, so once you have learned to use the system, new programs become more intuitive.
1d. Macs go wrong far, far less often than Windows machines ( I also do maintenance for an array of Windows machines)
1e. updates to the OS are free downloads. Always. You can always choose to download an older OS and re-install, if you prefer an older version.
1f. No driver installs. MacOS does not use drivers in the way Windows does - however, you may need to check that your existing printers and other peripherals are compatible with MacOS
2 Build quality
2a, Simply the best. They are made from (recycled) aluminium and are very robust.
2b. Sound quality is great, despite small speakers
2c. Screens are high resolution and bright, vibrant colours.
2d Internal drives are SSD, so very fast start-up and file transfer
2e They are pretty compared to the black plastic Windows boxes.
2f, the keyboards are very low travel and permit fast typing. However, try one out, as some people do not like them. Personally, I love them.
2g. Illuminated keys with variable brightness.
3 Included software
3a, all the software you need for normal usage is included.
3b, (might be good or bad) Macs are the platform of choice of almost all graphics professionals, so the pro software (Adobe family; Movie editing etc) is usually designed primarily for Macs with WIndows as the secondary choice.
Balancing factors
1. Far fewer games are available for Mac platform compared to Windows platform.
2. if you buy software, Mac variants tend to be more expensive than Windows (but you shouldn't really need to buy any, unless you are a specialist).
3. The base Apple machines tend to be a bit under-powered, so you might want to add even more money for RAM memory or storage, to make it a useful machine.
4. All web-based software, such as GoogleMail work just as well on a Mac compared with the Windows unit.
5. Thunderbird, Firefox, Chrome and other browsers/email clients work just as well on a Mac as PC.
Overall, if you have the money, I do not believe you willl ever regret buying a Mac, unless you don't get sufficient RAM/storage at purchase. Current generation Macs are not easy to upgrade from the delivered model - sometimes you can add more memory, but check before you buy
