I am looking to buy an SUV, but l can not make up my mind. Any suggestions?

None of those. The new Lincoln Nav. or the Porsche Cayenne

BMW is the best of them all in most respects

however, l would rather get an X6 over and X5 just cuz it looks a lot better

BMW X5.

l would not even consider a Hummer or a Land Rover. Land Rovers look nice but they r literally the worst made car on the road. They have ranked last in overall reliability 10 years running.

The Hummer is not as unreliable as the Land Rover, but they still r not that great & depreciate quickly.

The X5 has an interior comparable to the Land Rover, but the reliability & resale r much better.
This is an easy choice...go with the X5.

Hands down the BMW X5. It has free maintenance for the first 4 years or 48,000 miles. In my opinion the BMW also looks the best & is the quickest.

The Hummer is ugly, is under-powered, gets bad gas mileage, & looks like a wannabe H2. Plus, GM is trying to sell Hummer to a company in India, & who knows what kind of customer service u will get then.

The Land Rover was also just sold to a company in India too, not to mention they have horrible re-sale value, plus all that ugly black plastic on the body.

This is just my opinion of course

bmw by far. but if you can afford the porsche cayenne go for it. its another level above any of these cars.

oh yeah the hummer is great on gas
