Use both & then decide

Linux is faster on older system, there is no gaming in it, drivers are hard to find, but old hardware is certainly supported fine. U get Windows alternative for all the applications in it, except for a few, but for that u can install Wine. It secure cos it has low desktop market share compared to Windows, so u won't need to install Antivirus or firewall, as most of the adwares etc out there affect Windows only, but this also makes it less compatible, like there is no Shockwave player for linux, but u won't miss it anyway.

Remember, if u r going to use linux, u need an Urge to learn

Windows is easy, it just works, there is little need to configure it, it can be molded in anything u like, don't need to learn anything in it, just install it, install the software, there are free alternative to every paid alternative in Windows too. Just install the Windows updates & some free antivirus like AVG, the inbuilt firewall works fine most of the time, but u can install again some free firewalls etc for it.

If u don't like IE switch to Firefox or Opera, u will miss a lot of compatibility though
