I liked acts_as_authenticated. Simple, understandable yet malleable. The engines stuff has been horribly buggy, at least when I tried it last. I wouldn't choose based on popularity. The Login Engine and User Engine are far more popular than they deserve to be.

the whole transfer to google seems screwed up. Not only am I getting individual messages instead of the digest, the unsubscribe is in an infinite loop. Please someone deal with this issue. One other nit - I bloody well resent being forced to choose a nickname. Its utterly my business whether or not i have one. stupid stupid stupid.
strange. worked for me..
i subscribed with a normal non-gmail address, and via gmail and setup a forward. the latter's emails are easily arriving 10-15 minutes before the other, or almost instantaneous.
bottom line, if you want prompt delivery, use gmail 
kind of reminds me of the stuff in IIS that would deliver requests to IE users first..
I totally don't understand oyour issue. If you prefer daily digests... Change the setting to daily digest. Regarding the nickname i totally don't understand at all. There are always some name to represent you..... Do you prefer using only you email??? Then use your email as nickname.... It's a mailing list.... There is little difference between this and the old one.
i'm on the ruby list but my subscription was deactivated a long time ago. i now seem to be getting emails.
i like acts_as_auth as well. tried User/Login engine and realized i liked more the ability to get in the code and extend/change. AAA's generators allow for that easier than the Engine approach.

I’ve yet to see a good “slap this in and you have a full admin panel w/ user controls” type of engine/plugin. The simple stuff is easy to build on, but i’d love to hear about something already done.
one of the user (engines or otherwise) + the streamlined[1] framework will get you pretty close…

I would look at activerbac https://activerbac.turingstudio.com/trac if you have complex needs. Its not flashy but its fully done and has everything I have ever needed, or could be easily added.
