Why is Sukhumvit so popular?

I'm curious to know, why is Sukhumvit such a popular destination? Is it the vibrant nightlife, the diverse range of cuisines, or perhaps the convenience of its central location in Bangkok? Are there any specific attractions or landmarks that draw visitors to Sukhumvit? And what makes it stand out compared to other areas in the city? I'd love to hear your insights on this popular Thai destination.
