No expert here either, but I tend to go the Av-route kiwi_jono already mentioned.
I've found that exposure is indeed stable enough to work with. And by that I mean stable enough for a program like
LR timelapse to smoothen out any flickering that might (and will) occur while keeping a natural look.
Ultimately it depends on what kind of look you're aiming to achieve: Personally I like shooting this way during a sunset as it will show more details in of what is going on in the dark (which depends on your subject really). Moreover, having exposure times go up leads to more motion in the images (such as lighttrails of cars driving by).
