do some searches on here and other sites. Your question is pretty broad and there is a ton of feedback. You will find failures on all the models, including Leica. I am strictly a rifle hunter and hunt were 400 yard shots are very common and longer do happen so my emphasis is different that yours.
My personal experience is with a Nikon 1200, and for $350, I can not complain as it reads consistently, the functions are simple, and it has lasted me almost 7 years with only 1 battery change!
