I recently got a cheap drone, and the image quality and smoothness is incomparable. Definitely worth the money for a good drone if you want the best quality of video and photos. I really bought mine as a starter drone, to get used to flying them on something cheap, and to see how much I used it, before dropping a bunch of money on a good one like this one.
You'll find flying the better ones much better as well.
Enjoying the scenery. I was surprised you were able to capture so much footage of the trains and tracks. Around here they tend to be pretty stringent with so many things. Have fun with it.
