Hi Arkasha , there is one thing that has not been mentioned so far on the differances between the two , and that is the length of the light path thru the diagonal .
Some scopes can reach focus using a prisim and some wont ,as the prisim diagonal has a longer light path , eg. the light has to travel further to reach the focus of the eyepiece ,
.
My Zeiss has a prisim diagonal , but I use a William Optics mirror diagonal in it most times because almost every eyepiece I have wont come to focus using the Excellent Zeiss prisim Diagonal
.
Its a shame , as the Zeiss one gives true'r images ( colour fidelity? ) when compared to the WO dieletric , more true to life? the Zeiss looks and the WO looks clinical , really sharp views , and if the Zeiss was not around , no body would see that differance. .
Its hard to explain , the beauty is in the eye of the beholder , I think ( my eye ) .
So what ever does it for you , get one that suits you ,its gotta be better than none at all .
Brian..
