I see it the other way. Trolleybuses (with either battery or diesel backup) are the best of both worlds. Much cheaper to built (compared to a tram) and doesn’t pollute in the city (compared to a full diesel bus)
Trams are surely better, but the simple infrastructure and relative simplicity of the drive train make trolley often cheaper than a diesel bus. Trolley buses with a small battery can also deviate from standard lines or bridge small areas between trolley lines.
When I was there I found those busses really cool. But to my knowledge, they’re being phased out. They essentially combine the worst of bus and tram:

Best solution: trams (or streetcars, for Americans)
The fact that “streetcar” means something unrelated to both a street and a car is above my IQ

Trolleybuses are the best compromise because they can (and in my country/city do) work as diesel/battery buses
