I like them both and very much. But if you make me chose one, I'd say spinach. I really love vegetables from all kinds. I don't mind eat them, I even enjoy. I don't know why many people tend to dislike them (well, I can recognise when I was younger I wasn't too much in to them as well, but I never disliked them at all).
Well, nice that at least you don't find it disgusting (I dunno why has fame to do so, but anyway). Maybe not the most pleasant food, but is not a torture neither. When comes to me I eat it with joy, since I'm vegetarian, I already got used at this.
