Your experience sure is "backwords" to most other ones on here!
For Starters, does your Stihl chain say "made in Switzerland" on the box or drum - if not, it is not the same Stihl chain that we usually discuss here......
I agree that my experience does buck the US/European trend but certainly not the Australian trend. Only one person I know that spends a lot of time on saws cutting Aussie hardwood, in particular dead, dirty hardwood uses Stihl chain. He didn't want Carlton anymore because it was "too hard to file".
A lot of guys that bought their Stihl saws with Stihl chain assume that its the best chain on the planet because 1) It's branded Stihl who have a really good name and are well known, 2) They've read all the rave reviews about RSC (for example) on this site, and 3) They've never actually given a variety of chain brands a serious workout in a direct comparison (but maybe they have in their conditions?).
As I've mentioned before, the fact that the vast majority of guys on this site use solely full chisel suggests that they're not really cutting in conditions that I would consider are tough/abrasive on a chain. A lot of guys also sound like they touch up their chains before they're actually blunt (a good habit) so therefore never get a true representation of chain wear.
And yeah its Swiss made Stihl chain. If I was cutting green, clean wood everyday in high rainfall forests with grass around my feet maybe I'd like Stihl too? Unfortunately I'm too busy choking on dust, cleaning/swapping air filters, swapping chains, and fighting off blowflies
A while back I made a half/half loop of Carlton 3/8" semi chisel and Stihl 3/8" semi chisel (72DL, .063"). I've posted this before but in the exact same conditions the Stihl bluntened considerably faster and was visibly more damaged than the Carlton. You don't get much more of a direct comparison than two chains on the same loop at the same time. I'm not trying to bag Stihl, I generally like their gear, but in mine and other Aussie's experience it just doesn't hold up as well as the others in tough conditions.
It's not that Aussie's don't have access to Stihl chain, around every corner there is a dealer, but a lot of guys that do a lot of cutting won't use it - the fact that many Stihl dealers are a rip off doesn't help either though
Not trying to start an argument but I do tend to get a warm fuzzy feeling when someone on this site even acknowledges that there are other chains out there at least as good as, or better, than Stihl.
