Need your thoughts on which is better - the Kohler Command Pro horizontal motor or the Briggs Professional Vertical shaft motor. Everything else is equivalent - pumps, motors, decks are all the same. Only the motor changes. Kohler is a 23, Briggs a 26 - air filtration is Canister type on the Kohler, flat automotive type on the Briggs. Oil filtration is the same on both. I'm looking at these for the long run and interested in what you have to say.
