The WP is better built in many ways and is larger in capacity.

The WP has a better idler pulley, it has four rollers no cheap plastic slides for drum support, WP also has a blower that will stay attached to the motor and a steel blower housing and lint filter duct so it is less of a fire hazard and a metal lint screen.

All that said I still like the 29" wide WP dryers better overall.

The larger diameter drum lets jeans etc fluff out better and leaves less wrinkles.  

The air-flow pattern is just better in the 29" dryer, It is almost unheard of to see any serious lint clogging in the lint-filter housing and blower of the 29" machine.

I had this dryer in gas as well, now have a newer version Duet, also gas.  Over the years, I've had several 27" WP/KM dryers all gas.  It's a very fine dryer for big loads, the combination control units that use temperature and moisture sensing are quite accurate most of the time, but as John points out, the narrower, deep drum tends to roll the load.  Larger and bulky items tend to roll into a ball and I get an hour of thumpy tumbling and damp middle at the end.

Dryer balls in this model tend to ride the front of the drum and lazily hang out on top the filter housing.  It's better with regular clothing loads, but blankets and like tend to push the balls up front.

Despite the minor gripes, it's a fast and efficient dryer overall and you can't stack a 29" WP.
