I have been using SpeedLight in both my iPad Pro and my iPhone for about a month now, and I must say that I am pretty much satisfied. It will depend on which usage each of us does of their SL for sure, and you have to keep in mind that SpeedLight is a W-I-P kinda thing. But overall, and as a change from computer-only-SL to mobility-allowed-SL, I find that SpeedLight does most of the job for me - I’d add a couple things to it, and have by now told the developer. I have not tried Lumiya, as I am an Apple user, but I would recommend SpeedLight.
Just hope this is helpful. Have a great day!
