>performanceThis doesn't really matter, since the whole tram system is slow due to speed limits, frequent stops and traffic lights.
>energy efficencyOnly difference between the old units and for example the newer Transtech Artics are the fact that Artics and take back the electricity when it's braking.
>passenger amenitiesThe older units have more standing room and the loved single person seats. The older units have a next stop-screen, just like the newer ones.
>safety are worse Well, there's a buffer on the front of the older vehicles, which might hurt when you get hit by them.
Reason why HKL (Helsinki City Transport) still uses the old vehicles, refurbishes them and has gotten the new Artic-model is to replace the Variotram (pic related), which is known to be a noisy, shaky, unreliable and generally just a shitty tram and a mistake that is Bombardier vehicles (at the time, looks like the Stadler Varios are much better).
