My two favorite WP8 phones are the 8X and the 925. I have a great respect for the 920, and I still have some pictures from that phone, but I loved me some 8X and 925. My favorite Windows phones so far are (in order):
Samsung Focus S, Lumia 925, HTC 8X, HTC Mozart, Lumia 920, HTC M8, HTC Titan.
None of these will see Windows 10, except for the M8 via insiders. Just sad all around, but this is why I didn't buy a 950 or XL...they're nice but lack personality and soul for me. All the devices listed above I truly enjoyed because they had some quirk about them that made them personal. From the toughness of the 920 to the sexy designs of the 8X and 925 to the raw industrial big screen feel of the Titan to the simple ruggedness of the Focus S to the compact nature of the Mozart, these were my favorites.
For the record the HTC Touch Diamond is my all time favorite Windows based phone. A distant second and third place lies the HTC Kaiser and the Xperia X1...then comes the list I mentioned above.
It's just sad all around now, but I guess if you're vested in the MSFT ecosystem, there's a lot to look forward to still...
