I think I prefer straight prose, since I found myself having to read descriptions in 3rd edition anyway; and find straight mechanics requiring no adjudication to be too... well, mechanical. The 5e spells I saw seemed very straightforward and elegant in their presentation. If anything, the main thing I think I missed from previous editions was a listing of required components. I always thought that was great flavor, in part because it was so ignorable and outside the straight crunch of the game.
In any case, I always had a piece of notebook paper to track my memorized spells in 3rd edition and Pathfinder, which I wrote down page numbers and whatever other info I felt I needed to know; and think there's usually enough time between turns in a normal-sized group to look up a spell and parse a paragraph. 4ed made things much simpler, but in a way I think grabbing for a book and reading through a spell got ingrained into me as part of the Wizard-playing experience from previous editions, and I found myself missing it.
