I quite like the cases, personally. If you're not in a more formal context or writing (like say you're talking to friends or so) it lets you be a bit more fast and loose with word order, plus it can let you say things more concisely than you can with english. The only real solid annoyances I've had were adjectives. Learning all of the rules and endings around them sucked on some level and it felt really quite superfluous, but once you get them and you can gauge correctness just based on it "sounding right" it's not so bad.
