I'm not a carver, I have carved only once and result was not much, but certainly I will try some other time, however I have few experiences with electric saws and own a few so I try to share what I have learned.
Electric saw that I use most is Jonsered EL-14 from ~1990 that is still running strong, it is built such way that it will last almost forever as it has a clutch that is engaged normally and slips if chains gets stuck or one pushes too hard.
Clutch has also sprocket like normal saws, not sure where to get replacements at this age though as saw is ancient history in electronics world.
Good bit on that saw is that it is fairly light, slim body, has handle that somewhat resembles handle of normal saw, so you can operate it on it's side too if needed, also bar is same as on 345 husky or 2145 Jonsered saws, which means there is plenty of bar options available.
Bad bit is that chain speed is fairly low and .325 .058 chain is bit much for 1400 watt saw, also finding one might be a challenge, mine is around 26 years old.
Many modern electric saws seem to have motor mounted under the handle on side of the saw body, which in my opinion makes balance of saw quite terrible when all the weight is in motor and that is not centered to saw body.
Another thing to consider is throttle switch safety button, on some electric saws this is really stiff, which makes your thumb hurt after a minute of constant use.
On some lower price range products kick back system has brake band that tends to grab quite a bit even when squeezing throttle switch should release it, so good bit of saws power turns into heat and noise, so power they get to cutting is not always seen from how much power they draw.
