Should I ditch Constant Contact?

I'm doing work for a client who uses Constant Contact, and I'm thinking about recommending they switch to aweber. Here are 3 features they want, and I just don't think Constant Contact can do well, if at all. Suggestions are welcome!

1. NICE looking popover. There are very few plugins that work out of the box with constant contact, and they certainly don't look good or have advanced features that control how often it's displayed, turn off for members, etc. Anyone know of a good one I missed?

2. Ping for automatic add and removal from lists. We want to add a ping link to our membership plugin that will automatically add new paying members to a list, and move them back if they cancel their membership. Surely,there must be a way! But it must be "ping."

3. The ability to set rules. So, if someone is on a "non-member" list, they should be moved automatically to a "member" list, and back again if they cancel. I've done this in aweber, but I can't find this feature in CC at all.

Yes, I called CC and the guy couldn't help me. BUT, I know, that Warriors know more than CC support!

If they didn't have such a HUGE list already in CC, I wouldn't even hesitate. What are your thoughts?

Thanks!
