Best Small Emgine

I'm looking to replace my 42" garden tractor and will replace it with another of the same size. I've looked at most of what's out there and I see three main engine manufacturers, Briggs & Stratton, Kohler and Kawasaki. I'm looking for informed opinions on which is the better engine. Not necessarily which is better for the money but which is best. I know this forum has a number of members who make their living working on these things, so I'm sure there are plenty of opinions backed by experience.



Thanks,

Jim
