“HP is the amount of work an engine or motor can provide, torque is a result of HP. HP is more important than torque. What I believe the OP felt is nothing more than than a different power band. If an engine makes it's power at say 8,000 rpm vs say 10,000rpm it will give the illusion it has more low end, when all you're really doing is operating the engine in it's power band. Now operate the engine that makes it's power at a higher rpm than pull it down too far it will seem like it's under powered, when in fact you're simply not operating the engine properly.
A lot of truth in that, except the basics - power (hp or kW) actually is a function of both torque and rpm - you need both to get a high hp number, that just is a theoretical number for how much work the saw can do. It still is the torque and rpm that actually do the work - and then there is the chain and the sprocket gearing, that will have some impact on the rpm and cutting speed in practical cutting.
