Both pillion seats are an improvement over stock, at least on the 1st gen. I took my wife for a half day ride on the gel seat and she said she immediately liked it better than the stock seat on wich she hasn't had all that much seat time. She rode on the back of my corbin seat for a ride up to St. Louis. After four 10-11 hours days and one 8 hour day, the only complaint she had about the pillion seat was that it is smaller than both the stock and gel seats and doesn't give the passenger much room to move around. Otherwise, she liked it just fine.
