Superior:
- Far more secure (though I wager that if as many hackers targeted Linux as they did Windows, it would have just as many holes)
- There's about a thousand different distributions, so it's relatively easy to get one to suit your exact needs
- Cheaper than Windows if you buy/download it, though Windows is cheaper to get with a prebuilt PC (since it's already on it)
- It's most likely faster since Windows is 90% bloatware
Inferior:
- Horrendous driver support, though this is slowly improving
- Horrendous program compatibility - though more programmers are writing for Linux, there are generally superior platforms available on Windows
- Very bad for gamers, since the great percentage of games are built for Windows. Games which do support Linux are often not optimised for the platform either.
- No one standard - platforms mix and match different functionalities and features
- Windows is bloatware, but it has pretty much everything the everyday user needs and is also fairly user friendly. Linux in general is far harder to master for everyday Joe.
That's all I can think of for now. Both platforms have their advantages and disadvantages. Saying that one is unilaterally better than the other, Windows or Linux, is a lie, full stop.
