Looking for advice.

We are debating between either the old-fashioned boat from Duna Cruises or the more-modern Legenda boat. Children are 10 and 14 and want to have great views of the lit-up buildings. We would take the earliest evening cruise (I think it is around 8:30 and sunset will be around 8:40 or so...)

Is one of those boats just easier to see from? The actual vessel would be either the 19 century style one pictured here: https://dunacruises.com/en or the "Danube Legend" boat pictured here: https://legenda.hu/en/danube-legend

Also, does one of them have better commentary or are all of them now audio guides?

Thanks!
