Simone Biles has a pretty incredible ability to stick landings too. And, as
@skatingfan5 points out, Simone's floor routine had greater difficulty. Aly's landings were practically perfect, and Simone had a couple of very slight hops but they both overall had great execution. Judges take off requisite tenths of points for slight hops on landings. The difference in their scoring is obviously due to the difference in difficulty of their elements. I thought the scoring would be even closer between the two, but then I'm not an expert on gymnastics scoring.
To be honest, I haven't been following the sport that closely over the past ten years. I watch a little here and there, so I am fairly new to seeing and hearing a lot about Simone over the past couple of years and more-so in recent months. I was curious about what all the hype could be about. And then when I watched her performances, my jaw dropped. She's amazing.
You guys who have a beef with gymnasts' routines, and 'troubling' gymnastics trends, and/or gymnasts' sizes/ body shapes, what you gonna do about it?

I mean if you are long time fans and have been following the sport closely, aren't you able to understand why and how the current environment exists? The sport has clearly trended more and more to greater difficulty, more back-breaking tumbling passes, and an emphasis on strength and power. Simone Biles is an incredible athlete with amazing gifts. She maximizes her potential with the body she was born with. As do other athletes in every sport. Plus they all have to find ways to excel under the scoring system that exists in their sport.
