I own 3 four wheelers. Polaris Sportsman 500 and Yamaha Grizzly 660 and Polaris Sportsman 90 (kids)

Love all three! Before I bought the 2003 Grizzly I really checked out the field. 4 months of test rides, riding friends and reading reports. Here were my conclusions from the bigger machines:

Polaris - good overall, the best ride, the best brakes, very heavy, develop rattles
Honda- the best overall engineering, weak ride in bumps, Rincon they' re new machine is weak. Its not designed for utility use, its a trail riding machine. Foreman and Rubicon are excellant.
Kawisaki - Great power, weak ride, good pulling power, heavy.
Yamaha - Decent ride, good power and pulling, ok brakes, fairly light
Suzuki- doesn' t offer a big maching(600+) Weak ride in bumps
Artic cat-Doesn' t offer a big machine(600 +) They' re starting to figure it out.

Overall all these machines are pretty good. Light years from where they were 10 years ago. Each manufacturer has they' re strengths and weakness but once you know what you want the decision won' t be too hard. Example if you want an independant rear suspension for the best ride you can rule out Kawasaki, suzuki and Honda. Honda has the Rincon it looks real nice and has independant rear suspension but for hunters pulling deer or elk, working on food plots and hard general use, not an option. One more thing, you don' t need a 700, many 300 or 400 will do everything you could need!
