I would personally go with the Honda. Honda has proven reliability a kind of make sure it has fuel and oil and your okay to go mentality. I own 3 Honda quads and have had no trouble with any of them during my 3 years of owning them. But the 150 will be slower...250 would have more speed all around, but the 250 would also have what 3-4 years of god knows what kind of riding done to it. where as the 150 is a year old. Hope this can help.
