If I want a boiled egg, chances are I want it soft-boiled (runny yolk but cooked white) which is the custom here in the UK. (As children we are given a softboiled egg in an egg-cup along with rectangles of toast called "soldiers" to dip in the yolk. I guess it's an Edwardian thing, redolent of Nannies and Nurseries.)
In all my 50 years I still cannot reliably produce a softboiled egg, regardless of the method. Do I bring the water to the boil with the eggs already in the pan, then count from when it reaches the boil? How do I judge a "rolling boil"? Or do I wait for the water to boil then put the eggs in, risking cracking? How do I adjust the timing if I want to boil multiple eggs?
I can hardboil them but sometimes overcook them and get that sulphurous green yolk edge, or I forget to set an alarm and underboil them leading to an unpleasant surprise later of a partially-cooked egg white spilling out of my inedible egg.
For fried eggs in my stainless steel pan (I don't have any non-stick pans) unless I pre-heat for ~20mins, the egg sticks and I often end up having to chisel it out with the spatula and breaking the yolk which depending on my morning mood can be a real downer. Added to which the underside is usually cooked way before the top, and the egg white in the thickest part is still clear and snotty, so I will try to flip the egg, doubling my chances of breaking the yolk and killing my morning.
Scrambled eggs are nice but easy to overcook to a dry pebbly consistency, and unfailingly create a quarter-inch layer of crusted egg in the pan which goes to soak in the sink and return later in the day as a jellyish monstrosity to cling to my hand or be clawed dripping out of the plughole catcher.
I love a filled omelette, but again it's a crapshoot - too hot a pan and the egg goes hard and rubbery on the outside, too cold and the folding is difficult, especially with solid items in the filling.
My point is, boiling eggs is undeserving of its status as a byword for simplicity. It's getting to the stage (for me) where it's an object lesson in how much I can fuck up a seemingly simple thing.
