In my, reasonably extensive, experience of Apple lightning leads, the pattern ones are variable.
Trouble is, because of the supply chain for the pattern ones, one day Amazon might sell ones that plug in easily but the cables are fragile, next day, the cables are good but the plugs don't fit that well.
Which puts you in the realms of the branded (but not Apple) ones from the likes of Tesco. Trouble is, price wise, they are getting close to Apple outrageous pricing. And the Apple ones do last well, and fit perfectly.
Of the pattern ones, I have found the Poundland ones aren't too bad - slightly harder to plug in. But they start to fail after a few months.
I use the Poundland ones at work, and normally buy loads at a time. Namely because I don't go in the office often, and I can guarantee every time I do, the one I left on the desk has gone walkies. For charging at home, I use genuine apple.
