Is laminate flooring easier to install if compared to other flooring materials?
It depends on the tools you're using/have, and your skill level with said tools.

I've installed both "click-lock" laminate, and nail down hardwood flooring. Both took about the same amount of time, and used fairly similar installation techniques.  The major difference, was that the hardwood "required" a compressor and flooring nailer/stapler.

Linoleum and other sheet products are fairly easy to install, and don't really require any special tools.

Carpet is also not that difficult, as long as you have the tools and knowledge required to stretch it.

Obviously complex room shapes complicate the installation of each product.
