I didn't know about caltopo. So I can just give you my two cents from tinkering with it a little just now.
caltopo has a lot more map data with all the different overlays you can toggle. Also, you can add many more objects (polygons, sectors etc.) besides a simple route with waypoints. wanderer's route creation tool has been added only recently and is still quite rudimentary. It has automatic routing though (you define two points and the route between them is calculated automatically based on your selected mode of transport).
wanderer excels at cataloguing your trail data. You can attach a lot more meta information like photos, dates, comments or a summit logbook. It also allows you to search and filter your trails with many customisation options.
Lastly, and that is very much biased as well as personal preference: it looks a bit sleeker ;)
It looks like it's using Pocketbase as the DB. I've been using it in a Flutter app and have been thrilled with it. Definitely recommend it, especially a hosted instance on Pockethost
