The carpenters chainsaw I use is an old protool 380 running a 16" bar with square ground ripping chain. I use it mostly for cutting long curved timbers: sling braces, crucks, curved braces etc. While it follows a curve nicely the finish is certainly not as fine as a well tuned bandsaw. That said I am more than happy to leave it as is on a more rustic frame.
I haven't had any experience with the Mafell although apparently they have a very fine cutting chain for finish work. I am guessing that this is probably designed mainly with cross cutting work in mind and that you would have to push it like a mule to get it to rip along grain.
The saw certainly takes a bit of getting used to but the more I use it the more it is becoming the favorite tool in the shop.
