I think that I always knew that Darkseid should be Dark Side (or really Dark Zide), because that's how you would pronounce it in German. I hadn't taken any formal German yet in 1971, but I must've known some German pronunciation (given my family). The question in my mind was if that's what Jack Kirby intended. If he knew Yiddish, and German being close to Yiddish, then maybe. However, I thought it might be possible he meant it to sound more like Dark Shade. I never thought it should be Dark Seed, but guessed that many readers would say it like that. For me it was always Dark Side. The German pronunciation of the name is a good guess--because just look at him, he's wearing jack boots (so depressing when you look for images online and Kirby's original design doesn't come up).
