If its weight you are worried about then heres some info that you may find usefull.
Honda 90hp = 169kg = 0.533hp/kg
Honda 115hp = 225kg = 0.511hp/kg
Honda 130hp = 225kg = 0.578hp/kg
Honda 150hp = 220kg = 0.682hp/kg
Suzuki 90hp = 189kg = 0.476hp/kg
Suzuki 115hp = 189kg = 0.608hp/kg
Suzuki 140hp = 186kg = 0.752hp/kg
Suzuki 150hp = 211kg = 0.710hp/kg
Optimax 90hp = 170kg = 0.529hp/kg
Optimax 115hp = 170kg = 0.676hp/kg
Optimax 135hp = 195kg = 0.692hp/kg
Optimax 150hp = 195kg = 0.769hp/kg
So if you want a 90hp i reckon honda is the way to go.
At the 115hp level The Opti wins it.
At the 140hp mark Suzuki wins being lighter than the 130/135 offerings from the others.
But the outright winner is the 150 Optimax.
So I would say you have a choice between The Optimax 150 or the Suzuki 140 or the 115 Opti depending if you want ultra quiet / ultra efficient or you want the maximum power to weight ratio you can possibly get or the lightest engine you can possible get. I cant speak for the fuel economy of these fuel injected 2 strokes - i understand they are pretty good these days.
