Your questions seems like asking "What's the best grocery?" or "What's the best car?" No one can answer the question, but you will collect some opinions and anecdotes.
You would have to define "best" in terms of both how you intend to use a laptop, and your personal tastes and preferences. "Best" doesn't describe a quality of laptops, or a metric by which we can objectively compare laptops.
Personally I use an iPad Pro with keyboard as my personal and professional "laptop." Although it works for me and suits my preferences I would hesitate to recommend my setup to everyone or call it "the best." iPads do not (yet) have Copilot or other so-called AI features, though I expect that's coming, and I expect Apple will let me turn it off as they do now with Siri.
