Based on demand, I'd have to say Illuminations is the better cruise. I haven't been on either but I have checked into both and the responses I have gotten are varied. Illuminations is much more up close than Wishes. From what I understand, the music isn't piped into the boats so since you are out of the park for Wishes, you really only see the fireworks display. I have also heard that some people have experienced a good deal of smoke and ash from the Illuminations Cruise depending on which way the wind blows, though most have said it's not a problem. I called for three straight mornings to get an Illuminations cruise, booked a Wishes as a back up, and then, when I was able to get Illuminations, I cancelled the Wishes. There is a lot of info on the theme parks and stategies thread about both.....
