I like rotators for their collection of faucets; it makes it easy to go through a bunch of faucets at once.

What I don't like is rotators with bad UI's and slow loading times, and bad selection of faucets.

There used to be a faucet rotator called Bitcoin Hydrant that I really liked, it had a nice UI and the owner pruned all the faucets, but unfortunately, I think he abandoned the rotator.
