I'd go Leupold in this case. They are less expensive, although you can get a Zeiss in 3-9X40 right now for about $120 less than the Leupold. If you wanted to go that way it would be a tough decision. A 3.5-10X44 Zeiss will not be discounted.
The 3.5-10X44 Zeiss is about $730
A 3.5-10X40 Leupold is about $479
A 3-9X40 Zeiss is on sale for as little as $359
The Zeiss has better than average eye relief, but the Leupold still beats it by a bunch at low powers. The Zeiss is very slightly clearer.
But if you want lightweight the Leupold is 4 oz lighter and 2" shorter. A better combination an a trim lightweight rifle.
