If you want an engine that dead sticks on you in the air, get a brand other than OS.
Most dead sticks are caused by fuel line problems. O.S. is no more immune to this than any other brand.
I've over 34 non-os engines and there is no difference in the dead stick rates.
When I get a dead stick it is because of a fuel line problem, fuel depletion ( e.g. long downlines), mistuning, or as is usually the case that I'm merely let the tank get too low.

If you want an engine that won't hold it's value if you ever want to sell it, get a brand other than OS.
O.S. engines are more expensive up front to buy and more expensive to maintain because of the high cost of parts.
It is not that they "hold their value" better, but rather people seek more money when they go to sell them.
They get just as dirty as other engines, wear down at the same rate, etc.
Not that there is anything wrong with them.
I've purchased used O.S. engines then found that they were simply not worth renewing or repairing because of the high parts cost.

If you want bad fuel economy, get a brand other than OS.
If you are getting different fuel economy, then you have a tuning problem. It has nothing to do with the brand name.
My OS .75AX burns exactly the same amount of fuel as my CHEAP Tower Hobbies .75 engine, and both pull the same plane in exactly the same manner.
The OS was MUCH easier to break in though. The T.H. didn't come into it's own until I had run about a gallon through it.
