Best thing about using the app for me is having the quilling whistle active while still being able to control the train. Our youngest grandson prefers the app and knows it well. That pushes me to try it more often ( dinosaur alert! ).
Best thing about the remote for me is that I can use it outside better. I know the buttons by heart. Much easier to run one handed as well.
Both have many great features. I got lucky and had the WIFI running easily. I got the WIU from Ray's Electric trains and he upgraded the software before shipping it. The down side is I now need many more WIUs or I have to keep connected the only one I have to each layout. I want to add stands to hold Android pads around the layout when both hands aren't free.
As long as MTH keeps both relevant with DCS upgrades, I'll be using both. Your favorite, you'll decide. I'd highly recommend that any new user try out both at a store or train show.
