The short answer
Based on available data, the Mitsubishi Galant comes out ahead of the Nissan Altima 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
Sentiment is mixed and heavily dependent on the specific generation and powertrain. The Galant is widely recognized as a budget-friendly, functional, and generally reliable sedan, particularly in its naturally aspirated four-cylinder and V6 configurations. Long-term owner reports praise the vehicles for their durability, with examples cited reaching 548,000 km (340,000 miles) and 200,000+ miles with proper maintenance.
Best version to buy
Manual transmission, naturally aspirated models. For the 8th generation (circa 2003-2006), the 2.4L 4-cylinder (4G64) with a manual gearbox is cited as the most reliable and practical choice.
Known issues
Overall
Extremely negative sentiment regarding long-term reliability, dominated by widespread and severe criticism of the Continuously Variable Transmission (CVT). The CVT is described as a fundamental design flaw leading to premature failure, often between 80,000 and 150,000 miles, with replacement costs cited around $4,000. This issue is so pervasive it has spawned multiple class-action lawsuits, particularly for models from the 2010-2020 period.
Best version to buy
Insufficient owner data available to identify a consensus "best" model year or trim. Isolated positive anecdotes reference older models (e.g., 2002 Maxima, pre-2010 Altimas) with traditional automatic transmissions, but no specific Altima generation or trim receives repeated endorsement.

It has more power on its best-equipped version than the Nissan Altima, based on the data above. If efficiency matters more to you than outright power, the Nissan Altima is worth a closer look instead.
