I think you worded it incorrectly. Surely it should be "This one sucks..."

Deja View - the feeling that you've seen this post before.

The good: it allows other events to occur, so they don't end up massively queued up with your application unresponsive while you perform some complex task. The bad: it allows all other events to occur, so you can end up re-entering the current block of code and ultimately end up with stack overflow. Also, if you happen to include it in a COM callback, or a paint handler when you've already made a COM call to another process, and one of the events that fires tries to make a COM call to another process, you get a 'cannot call out within message filter' error. That one caused a lot of head-scratching, I can tell you. You end up having to break up your big routine littered with DoEvents into lots of little event handlers and somehow have a way of transferring control between them by some other object raising an event. Timers work, of course, but the minimum timer duration is about 15ms on Windows XP, which is eons in computing time. (I wrote a component in C++ which merely posts a message back to a hidden window, and raises an event when this occurs, cutting that down to tiny amounts.)

Whats good about VB, absolutely nothing, zilch.

It's a real shame they included this in .NET's WinForms implementation. I utterly rebuke any code that uses it. :) Thank God they didn't such an easily abusable API in WPF. In WinForms, if you really need to do lots of work and don't want to back up the UI thread, split up your work and execute it inside Application.Idle event. Much more scalable, no scary re-entry issues to deal with. Or alternately just use a background thread. :)
