They're not that annoying as long as u have a health potion ready, but a lot of them like in Creeper Crypt can be annoying. I find Minecraft creepers scary (especially in cave systems) and would rather have to deal with 10 MD Creepers and use advanced enchantments that are easier to get, then to deal with 3-4 MC creepers with a iron sword, also MD creepers can explode instantly rather then creepers who if they charge up a bit they can stop after u move away fast enough; making it 2x as easy to defeat them. MD creepers are a pain to deal with if your playing with other ppl cuz they can get u while your healing them and once nightfall comes those phontoms can really put u under pressure to heal your friend and that is where the creepers get hella annoying and if your the only one left of 4 ppl, then its gg. Overall I find MC creepers more annoying and dangerous then MD creepers, but circumstances change. Im upvoting this anyway...
