Out of interest what do you find better about Cycle Travel?
Simply put, I prefer the routes cycle travel creates and I trust the routes that it creates far more than any other planner (I do a bit of touring).
At home, I tried end to end routing on most of the apps and compared them to what I knew. Cycle.travel were consistently the best - for me.
I threw some routes together in about 15 minutes for a trip to Ireland. Home to Rotterdam, Hull to Holyhead, Dublin to hometown. Hometown to Belfast. Stranraer to Hull. Once I had a problem when a cut through a housing estate was blocked. Easily solved by staying on the main road. And once, in NL there was no scheduled ferry at the crossing - my fault for not checking, it was out of season. I wouldn't trust Komoot to do a route of that length.
You have to remember that those are subjective characteristics, and also, that I started exploring the gps world when I was in NL. I firmly believe that different planners may be more suitable in different places - I just haven't found that place yet for Komoot

and cycle.travel has worked and worked well in just about every place I've tried it.
It does have a tendency to route away from towns though.
It's also handy to be able to have direct contact with the developer! Is it bragging to mention that an entire country has been added to cycle.travel for my benefit! 😊 Richard posts on these fora.
With any planner you have to be ready for anything. With cycle.travel I have found the surprises far less.
I have tried Osmand (my backup), Google Maps, Strava, RWGPS, Komoot, Bikemap and one or two others. Cycle.travel wins hands down.
A worthy mention for Osmand. Not the greatest planner but it will work offline. With the right cable I can create a route to my specifications and get it onto my Wahoo with no internet connectivity at all.
