I've used both. For a point of reference, both were strung at 55 lbs as a full set.
Tension maintenance: neither is great, about the same.
Spin potential: due to the texture, they both have great access to spin.
Power: Alu power wins in this category with a little bit more pop.
Comfort: Adrenaline seems to be a little stiffer, but very similar.
I prefer to use Adrenaline Rough 16L, simply because it's $10 whereas the Alu power rough 16L is $17. Alu power is slightly better, but both are great strings.
