People will always tell you that whatever scope they have is the best one out there.
I would say that optics are something that you really need to try for yourself. Go to somewhere that has a good selection of scopes in stock and have a look through as many as you can to see what suits your eyes best.
I have been lucky enough to compare schmidt, zeiss, and Swarovski all side by side and after much deliberation it was the Swaro that gave the best image for me personally.
I went for a Z6i and it's a decision I have not regretted.
