The short answer
Based on available data, the Jeep Grand Cherokee comes out ahead of the Kia Borrego 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 sharply divided and heavily dependent on model year and generation. Long-term owner reports for the WK2 generation (approximately 2011-2021) indicate a pattern of initial satisfaction followed by significant reliability concerns, particularly after surpassing 100,000-120,000 miles. Owners of earlier models (e.g., 2005 with the 4.7L V8) express concerns about durability and high maintenance costs.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Isolated positive reports exist for the V8-powered models (e.g., Summit Reserve) for their power and towing capability, and for the Overland trim of the WK2 generation for its luxury features.

Overall
Owner sentiment is overwhelmingly positive, characterized by strong affection and reports of exceptional long-term reliability and durability. The vehicle is consistently praised as a robust, capable, and comfortable SUV that owners "loved" and kept for many years, often accumulating very high mileage (190,000 to over 240,000 miles/306,000-386,000 km) with minimal major issues. Its powerful V8 engine, body-on-frame construction, and high towing capacity are highlighted as key strengths.
Best version to buy
V8 model with 4WD/AWD and the towing package. The V8 engine is specifically praised for its power and reliability, and the 6-speed automatic transmission paired with it is noted as not having the design flaw present in the V6's 5-speed transmission.
