I think these are very different website designs. Either we go for a simple, "traditional" scrollable page, or we go for something fancy with a "slideshow" system. But each has its own advantages/disadvantages and there is no way to satisfy both at the same time.
Every now and then there is a new rage at making "everything fits in the screen" websites (there has been the flash epoch, then regularly new techs appeared after that), and after the rage passes, the trend always goes back to scrollable design.
And I like the fact that the user is in control of the "want to know more?" speed. You open the website, you get presented with the "top" part of the website. You want to know more? You scroll down. How fast you want to go look at the contents below is up to you. No need to wait for the seconds that the web designer thought appropriate to switch to the next slide. And having to click the little buttons to manually go to the next slide is way less practical than a simple scroll, which works nicely and as expected on both desktop and mobile computers.
My 2 cents
