Since no other responses, I will offer an opinion. Both are
likely Cummins ISB engines, and both likely DEF. Nothing
wrong with DEF, more horsepower and lower emissions
for any engine. The decision on which coach would be
the interior layout and how you plan to use it. The chassis
and engine are all secondary considerations. Either coach
will be a little slower on the big hills, but will give you
back better MPG. The horsepower is one matter, but the
torque is what gets you up the hills, and absent any knowledge
specific to the engines, I would guess they are in the 750
to 800 ftlb range.
