The short answer
Based on available data, the Maserati Quattroporte comes out ahead of the Maserati GranSport on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
The sentiment among owners is sharply divided, characterized by a high-emotion, low-logic appeal. The car is universally praised for its stunning design, intoxicating Ferrari-derived V8 engine sound, and the unique driving sensation and prestige it provides. Several long-term owners report positive reliability experiences with the 4.2L and 4.7L V8 engines, describing them as "pretty reliable." However, this is counterbalanced by very frequent and severe criticism regarding exorbitant maintenance and repair costs, poor long-term reliability leading to significant downtime, and the notorious unreliability of the Cambiocorsa automated manual transmission.
Best version to buy
Insufficient owner data available to distinguish a "best" version. Owner discussions refer broadly to the GranSport model without specifying trims or packages like the MC Victory.

Overall
Sentiment is sharply divided and heavily dependent on the specific generation and powertrain. The consensus indicates that the vehicle is a deeply emotional purchase driven by passion for its design, sound, and driving character, not rational ownership. The Ferrari-developed 4.7L V8 models (circa 2004-2013) are frequently described as "fantastic," "beautiful," "iconic," and "intoxicating" to drive, with a sublime engine note and a "classy, baller feel." However, these older V8 models are almost universally associated with very high maintenance costs, expensive parts, and a high likelihood of significant reliability issues, particularly with early automated manual ("F1") transmissions and electrical systems.
Best version to buy
The 2009-2013 Quattroporte S or GTS with the 4.7L Ferrari-derived V8 and the ZF automatic transmission is most frequently cited as the desirable version. This configuration is praised for its glorious engine, improved transmission reliability over the earlier "F1" automated manual, and the classic Pininfarina design.
