The are two reasons which is why I prefer to use Mega:
1. The downloads aren't limited (though which applies to the alternatives like Nopy as well, but I mean in general)
2. I can pause and continue it at any point (not just pause, but close the application which I am downloading from)
My download speed is around 1.3MB/s, but I prefer using the application in case I have to shutdown my PC at any point, which isn't possible with browser downloader, which just cancel it. Additionally, I almost never download at full speed, because I want to be able to have some buffer so I still can do something else beside that.
1.6GB isn't too much for me, but just wanted to state my point of view, which can vary for others, for example because of higher or lower download speeds.
