It depends on how you do your Diplomatic Victory - if you use "backdoor diplomacy" i.e. have an extremely large population so that you can vote yourself in, then Diplomacy is the easiest victory. On higher levels, Spaceship is nearly impossible unless, ironically, you are in a position to do one of the more aggressive victories. If you play Culturally without using the culture slider, it is a very interesting game for sure. Personally, most of the time I don't play to win - I play to play! I tend to win however the dice fall (if I get involved in lots of wars then I go Dom/Conq... if I have good science cities then I will go for Spaceship etc) .... and if it looks like an AI will win, then my game becomes one of stopping them. Personally, I just like to play for special situations: In my first ViSa game here, I have a city with 130 food..... I am now trying to grow it all the way up to its max population - that's my idea of fun! I actually like the religious victory, I just wish there was a video for it. Finally, once Total Mastery is included, I'll always have that as the only victory available.
