I personally believe you are comparing apples and oranges. Sure, the cars are about the same size and they offer both four and six cylinder engines but you are trying to compare a front wheel drive only car with an All Wheel Drive only car and by definition, they are not the same thing. I have owned Toyotas, Honda, GM, and now a Subaru. Cars are only as reliable as the maintenance of them. I still own a 2006 Saab 9-3 and although a blower motor went out this year for $300, and an alternator went out in year 7 for another $300 - that is basically it. Does that make it unreliable after 144,000 miles? No. Is it less reliable than Toyota? Probably - but only slightly.
However, taking your question about reliablity - Toyota is probably most consistantly the most reliable brand out there. Subaru is pretty good too, but you are dealing with a far more complex platform with AWD and by nature, those have more issues.
You obviously did your research. Toyota only had problems with the 99 Camry V6 where engine sludge due to bad ventilation caused issues and engine failures prematurely. They fixed the problem in 2000. Subaru has had engine oil consumption issues - probably because of their boxer ddsign which places the cylinder head on the side. They get better handling cars but in about 10% of all built, they will start having engine oil consumption issues before or at 100,000. Not terrible, but it does happen. By the way, they have been improving the design since they started so used cars before 2010 are far worse than the cars built after 2010 as they started redesigning the engines then to reduce the early oil consumption issues - which is why it is down to about 10% now.
I live in CT where living on a 650 foot incline up a small mountain owning a front wheel drive car is not so great in the winter even with winter snow tires. So we replaced our Honda Accord with a 2017 Subaru Legacy. So far, so good and we have 43,000 on it so it is a high mileage car. Then again, I don't expect problems with it until about 100,000 and then I have a 10% chance for issues. For me, the Camry was not an option as the only front wheel drive car that has worked on this mountain is the old Saab which for some reason, has a better traction control feature than other GM cars and other brands. It still does not work as well as the Subaru, but it is at least acceptable in up to about 3-4 inches of snow.
