I have chainsaw, chop saw (Makita sliding compound mitre), hand held circular saw, jigsaws, and lots more to choose from.
Chainsaw only gets used when there is more than a wheelbarrow full of logs to cut.
The hand held circular saw gets used for pallets.
The chop saw gets used if it is ready set up (eg. cutting up offcuts from a job) or if there is a large quantity of timber to cut.
Jigsaw - never.
Most often used is a bowsaw.
They are supprisingly quick at cutting. I've taken down 30ft high trees with just a bowsaw, and I could probably cut a wheel barrow full of firewood from battens in the time it would take to get the chop saw and extention lead out of the garage!
