I miss it too. For me, the replacement is Web. It lacks VB's all-in-one-ness, and it lacks the GUI designer, but other than that, I can get a pretty close approximation of GUI toolkit with events binding.
I don't use almost any frameworks or toolkits, save for a cryptography module, and I am quite happy and getting a similar experience.
Bonus is if I keep it to 2010-ish era DOM-style code, I virtually never have to worry about cross-browser compatibility issues.
I feel like VB6 was definitely a peak of the integration of beginning and advanced. I wonder if there's anything like it but for HTML, CSS, JS. The style of VB coding is basically frontend webdev today.
