I think Windows tablets are the best type of tablets for browsing the most types of websites because Windows still support Adobe Flash, Java, Silverlight, and other plug-ins which are not available on iOS, and Android.
The web browsers for Windows also work better than most mobile browsers which I have use.
There are also some add-ons which let Windows web browsers like Chrome, and Firefox show the mobile version of the site when you are using a web browser in tablet mode.
Most Intel CPUs are also faster than CPUs on cheaper Android tablets like the Asus Nexus 7 2012 Google Android tablet, and Android Tablets which uses Chinese CPUs, so Windows Intel tablets should run pretty well when web browsing.
