While I don't own one, I have experience with the Jotul stoves.
They are TOP NOTCH.
There's a strong American tendency to "Go Big" and there are times when that is appropriate. However, unless you need to heat a large, poorly insulated space OR bank a fire so that the stove can burn for hours without attention - a high quality, small stove has a lot going for it.
It is always more efficient to run a small fire hot than to run a big fire cold. If you pack a stove full of wood and then choke the air off, a lot of the potential heat of that fuel goes up the chimney in the form of smoke and creosote. You are losing potential heat and making a mess of your chimney.
If you run a big stove hot (lots of wood, fed by lots of air) you can end up with too much heat, particularly in a small, well insulated home. The answer is a small, high quality, efficient stove. The price you pay for that efficiency is you must tend the stove a bit more often (there's no free lunch in life).
The Jotul design extracts the maximum amount of potential heat from the minimum amount of wood. They are well made stoves with excellent castings. They are a bit on the expensive side and you can't get a lot of wood in the stove, so they're not the best choice for primary heat sources where the stove must be unattended for long periods of time (like if you have to leave for work and will not return for 10+ hours).
A couple of situations where the little Jotul stoves thrive are climates where it is often cold in the morning but warms to above freezing nearly every day. Or, supplementing the primary heating system and it's not critical that the fire burn for many hours unattended.
Many of the Jotul stoves are non-catalytic but have a "smoke box" to help recover some heat that would normally be lost up the chimney.
The Jotul 602 is small but an excellent little stove. I wouldn't hesitate for a second to buy a good used Jotul 118.
