Currently I am lucky enough to own both Zeiss & Swarovski scopes. The Zeiss is my favorite for several reasons:
The light gathering is superb, as Skany reports; I can still shoot well after the light is so poor that I cannot see by the naked eye any quarry (100-200yds).
The parralax side wheel is very convenient and functions well.
Overall the scope is 'quality' at a reasonable price.
Well worth saving up the extra ££ for.

Peter
