I got Latesttweets because it is the only 3.2 compatible twitter module that will display tweets from multiple twitter accounts. This feature works well, and is simple to set up.
What is missing are options to customize the look, such displaying the avatar or not, choosing between displaying the twitter username or real name etc.
This would be worth the $$ if it had all the options that the free modules have, plus the ability to display multiple feeds. Responsive would be nice too.
On the plus side it looks very nice, and like the options you have, if only they worked.
Support is very good, with excellent documentation which is rare in the Joomla extension world. All options are explained very well in the documentation, and makes this very easy to set up.
The software itself works as you would expect it to, and is very powerful.
The documentation is okay, and the support is good, although it was a little over my head, but got me headed in the right direction.
