Prague, Vienna and Budapest or Copenhagen, Amsterdam and Brussels?

Doing a two week trip in the beginning of August and can’t decide on an itinerary (I have a route planned for either one, starting in Germany). I know the second one is going to be more expensive but are the locations worth the extra cost? Looking for thoughts and opinions from people who have been to these locations!
I’m also going with someone with limited mobility if that changes anything. Was thinking about renting scooters to help with that. Thanks!
