Speed needs the exact opposite of aggressive in the skates.
It depends on what tricks you want to do.
Grinding needs to have the grind plates on the soles and H blocks between the middle two wheels that are only available on aggressive skates which are heavy and have tiny, hard, wheels.
Landing from higher drops require the tiny hard wheels.
Speed needs much larger, softer wheels. It helps if the boots are more flexible than the armored ones on aggressive skates.
If you are ok not doing grinding or the big drops but want to do jumps from the ground, ramps, or drops of a couple feet, you can consider freestyle skates. They will have normal sized wheels (around 80mm) which can give you reasonable speeds and are both durable enough and maneuverable enough to do the milder tricks. The big thing with freestyle skaters is foot movement around cones.
