In my oppinion, agility is more practical because of storage under the seat
and gives you more comfort during everyday use.
Also, there is a usable rear seat and gives you better image.
Don't get me wrong
I like tomos machines and have both agility 50 and a tomos 14M model from 1982
50 cc, 7 hp, 5 speed and hitting 65 mph
awesome machine, but ST is different kind of machine
Anyway, my vote goes to agility
