How does Audi A4 compare to Acura TSX?

[potential Audi buyer]

I am considering purchasing a 2008 Audi A4 2.0T CVT. This is the FWD automatic model. According to popular car comparison sources, it is very similar to the Acura TSX 4dr sedan, in term of performance and price, I think. Personally I like the style of Audi better. The car feels less sporty and more luxury than the Acura, and I like that. However, what seriously is holding me back right now is the concern of reliability. Acura is known to be very reliable, while as the Audi (even the models from recent years) has very mixed review for reliability, some of them very bad. I was used to having a Japanese car (97 Accord) and never had to worry about the car breaking down. Is buying an Audi A4 not a good idea? Any sharing of your experience with either A4 or TSX will be helpful! Thank you in advance!
Thanks everyone for your valuable suggestions! You guys have given some of the best advices I've got so far! I do intend to keep the car for a long time, if that's possible. I don't really like Acura for the same reason as Jay mentioned, although it's probably a great car!

So now I am looking into the Lexus IS250. Reliability is not a issue. For a couple grands extra, I get a peace of mind, although the style may not be my top choice. But not sure how the car IS250 "feels", never drove a RWD before myself. Any comparison there?

Still thinking if I can get away with an Audi A4. Why so few of them around? I counted 3 Audi in 4 days.

I have driven both of these cars.
Both have around 200HP and the same performance.
But if you are only getting the FWD model, then go with the Acura.
The Acura is the most reliable luxury car you can buy.
I would not buy an Audi unless it was AWD because they are famous for their AWD systems. I also like the style of the Audi better and the interior design. But the Acura would be cheaper to maintain and fix.
