Late game he's mostly just an annoyance but with his versatility he transitions well into a supporty-bruiser late game.. Especially now that Twitch and Eve got reworked, you're going to see a lot more of them so Lee will be a good pick versus them.
He's not the BEST at any place or stage in the game but he is a jack of all trades, so to speak.. Meaning that he can solo-top decently, jungle decently, and do fairly well throughout the game assuming you're an experienced player with him and can adjust your mindset based on how you are doing compared to the enemy team.
With lots of early kills/ganks, he can be a wrecking machine.. without them, you have to take a more defensive mindset and use your abilities to assist your team for the greater good. Sticking to a carry with a tanky Lee Sin can be quite effective,
