Would have to specify the size for under $1,000 / £1,000, but I'd say Zeiss dominates most of this space:
1. 8x25 size: Zeiss Victory Pocket, unquestionably the best optically in it's class. Superb build, Alpha glass. Outstanding brightness and sharpness. Superb control of CA, in the middle at least. Retired my 8x32 Conquest HD thanks to it's exemplary performance and portability (it was actually brighter than the larger 8x32 Conquest in most daytime conditions!). Probably my personal favourite bin under 1k, and might just be my all time favourite.
2. 8x32 size: Undoubtedly the Conquest HD. Amazed that people even consider the Leica in this size. The Zeiss is the same size and weight, but is brighter, has less CA, a significantly wider FOV, and also has protective coatings vs the Trinovid. Leica wins slightly on design to me (but this is subjective, and even then it's just by a hair). Truly near Alpha-level optically. Near-mythical toughness, as evidenced by the Fieldsports video review torture test. Excellent value retention. Simply best in class.
3. 8x42 / 10x42: Still have to hand it to the Conquest HD here. The Leica Trinovid actually has superior ergonomics in this size (at least to those of us who prefer compactness). But optically, the Conquest HD still wins for the same reasons as above - it is brighter, has less CA, and a wider FOV.
Different story north of £1k / $1k - competition is much more fierce, but at the moment it might be Swarovski at the top of the heap.
