Yes, its a trade off. Personally I'd rather have more big slow fans than a few small fast ones. If exhausting the heat out the back means a single fast fan to blow it through the hsf stack its just not worth it when I can have 5 120mm fans running at half the noise level pulling the air through my case.
eh, I tend to define "blowers" as coolers that exclusively exhaust to the exterior, but I guess thats just semantics. Do you define this card as being cooled by a blower? The fins are in the same orientation so some airflow will be channeled out the back... Either way the point is that the Titan Z is also a compromised card from the sense of heat dump into the case since half the air flows out the back,
Generally a squirrel cage fan rather than an axial fan is one of the features that makes the extractor be labeled a "blower". So, just like you, I wouldn't call the Titan-Z cooler a blower.
