Ive got a leupold supposedly it ranges to 1000 yards but i cant get a return on real world objects unless its pretty huge at that distance. Practical usage most commercial models 600 ish is about it.
Get one with good optical clarity and is easy for you to use. Other than that in my limited experience they are pretty much identical
