Nowadays I mostly just do OMAD (one-meal-a-day) or close to it (eating window is about 1-3 hours) as it's simpler. Initially some will power was needed to stop myself from snacking in the evenings, but as long as I make sure I have a fair amount of protein in that one meal, it never seems to happen now.
Occasionally I'll do alternate-day if I feel 'stuffed' or had a big day of lots of calories (holidays, social events) - whatever is more convenient at the time.
Eggs really are quite incredible - a great mix of fat, protein and micronutrients. I can eat just 2 eggs and not even think about eating again for 5-8 hours.
Note! This won't work if you have bread with your eggs, or anything else that raises your blood sugar.
As far as I can tell they all work (N=1 and all that), so I'd say that whatever you find easier to actually do is what you should do - just keep it up as often as you can over time.
If you wanna get a little geeky about it like I was, could consider buying a Precision Xtra to measure your glucose and ketone levels. For me this was helpful because I could see changes in the numbers after changing my eating habits. Had I not seen that, I would have only my scale to see body weight, and would've just looked at that and thought "looks like nothing changed, maybe this isn't working / doing anything at all." This also allowed me to "gamify" the whole process a bit ("I wonder how low I can get these numbers to go? how long I can stay there?" ... etc).
