Most Taurus handguns are perfectly good guns. That's why people don't sell them. Of course, people don't sell a lot of good guns. In the last 25 years, I think I've sold only 2 or 3. The rest stay in my collection.
Taurus haters are a very vocal group, but I think they're the minority. They frustrate me as much as the Taurus lovers sometimes do.
For instance: I see way too often a post about someone who's Taurus broke on them. Instantly, they've just decided that all Taurus are total crap, and they'll never buy one again.
Then, someone else will say their S&W broke (or their Colt/Ruger/Springfield), and you'll hear, "It must have been a lemon. Just send it in and get it fixed."
I do agree, though, that Taurus Customer Service is probably lacking the other big companies. I doubt it's any different from the smaller manufacturers, though.
I believe that ALL guns are going to sometimes break. Accept that. Some models are more likely to have problems than others. For me, it seems I've seen more Taurus model 85 problems on this forum than any other, but maybe that's just the model that stuck in my head. In any case, I'd probably avoid that one.
I've personally had a Walther, Glock, and Beretta with problems, at one time or another. I've never had a problem with a Taurus.
Anytime you want to buy a gun, take the time to go over the gun and look at how it functions, and how the parts fit. Double-check your gun often. I got a Marlin 336 from a family member a while back, and some of the screws had worked themselves very loose. This can happen with any gun, as well.
If you're interested in a Taurus revolver, ask to look at a similar S&W revolver. Spend the time comparing the two. How to the cylinders feel? How is the trigger? Hammer? So forth. Look at the finish on both of them. Do you see machining marks on one or both of them?
If you are interested in the PT-92, ask to look at the Beretta also. And so forth.
If you don't know what you're looking for, ask a knowledgeable friend to come along with you.
If you do this, then whether or not you buy the Taurus or the other gun, hopefully you'll get the best gun for your needs and budget.
