Again, they are. In the limited perspective of only working on front drive transaxles, they're much the same.
Working on economy three speeds or automatics from 30+ years ago, they are a nest of snakes. In those days you could drop the driveshaft by loosening four nuts, 4-6 transmission bolts, and then out. 30 minutes was very practical.
The average DIY who has never done it, not so much. Please don't overstate it. There are posts on the internet about owners trying to clock the TC and not accomplishing it for three months. Their set of instructions never mentioned the third internal tube which has to mate correctly. All they get is a pic of one half an inch too far out. Nobody even mentions test fitting the starter to see if you have it right.
They are apparently not the accomplished professionals others seem to be. If you have been down that road many times, bragging about it doesn't make it easier for the new guy. He needs the details and cautions. Who has mentioned it in the thread for the OP? An AWD transaxle is a piece of cake only if you already have the skills. Many do not.
It's what keeps the dealer in business, and reading up Subaru threads, the business is really good with this demographic. Most of the owners have extremely limited skills. The much smaller group of those who do work on them are much the opposite. But, mechanical competence doesn't equate to posting skills, either.
Nope, you don't have to disco a lot of the suspension to get the axles out, but claiming they just pop out, not so much. That is a high level skill trick many aren't going to finesse the first time out. Removing the lower control arms, OK. Pulling the nuts off the top of the strut will do it, too. OR - you can remove the lower strut bolts at the camber adjustment/spindle and re-install them by the witness marks you left on them. Lots of ways to do it.
Not all that common to find on the internet tho. If we keep it up, we might be able to catalog all of them here, the OP certainly will benefit. Then he can make an informed choice and do what he needs.
