Wapping, given the amount of effort you put into trying to get the Connected App/TFT to perform satisfactorily, are you still using it with MRA, or have you kicked it into touch?
I still use the Connected App / TFT, running bespoke routes that I’ve created in MyRoute. I run it via a scraficial Android phone which sits, either in the (undersized) cubbyhole or, more usually, in a powered tank bag.
As Mzokk does, I sometimes have all three (XT, sacrificial iPhone and sacrificial Android) all running the same MyRoute route simultaneously. Why? Simply because I can then see how they each differ in use. The all have their qualities and quirks. Which is better? That’s a very good question, the answer to which will be very much down to personal taste and / or experience gained through use. That said, as Mzokk said, the phone based MyRoute Navigation app is now very good as a standalone navigation device, just on its own. Would I use it if it was running on anything but a sacrificial phone? No.
Once you like the MyRoute Navigation app, you might as well create bespoke routes in MyRoute, too. The advantages of a cloud based app and ‘library of routes’ over say, Garmin’s BaseCamp are pretty obvious. Similarly, its ability to send routes from the app to my XT very reliably is a clear bonus, too.
Others will have other opinions, hardware, apps and uses, which is great. Each to their own.
