Its pretty powerful, and once you know how to use it, pretty easy. Review collected by and hosted on G2.com.
Initial learning curve is steep. Hard to know what function/ ingredient to use for what we need to do. Error handling is harder than SSIS (you need some knowledge of java) Review collected by and hosted on G2.com.
There is an open source version which allows you to get started. It has 100s of connectors to connect to Salesforce, SAP, Oracle, ODBC, JDBC, XML, Access, flat files. Also a whole host of other components WebServices, FTP and Email. The transformation tools allow you to manipulate data. The paid for version includes Data Quality tools, Management & Monitoring of data integrations but I have to say I've only needed to upgrade once for a client. It is incredibly powerful for what you get. What I also love is that its built in Eclipse and I know that if if doesn't have a component I can always write one. It has an App Store where users have contributed components.
Unlike competitors you can easily go under the covers and write simple Java code to manipulate your data. Review collected by and hosted on G2.com.
It does have a bit a learning curve but has some great resources online. The application does have a couple of "gottyas" which soon pick up but can be a bit of a pain when learning. Review collected by and hosted on G2.com.
I have used Talend many times to integrate with old legacy systems, that typically don't have a standard API or connector (due to their age and being completely a ground up custom system) The interface is very clear, and the visual capability of seeing via a flow chart where data is coming from, what is happening to it (translation) and where it is going is a really great feature. The Data mapping side is very powerful. I did not use the standard connectors (as it was custom applications I was connecting to) however I can see them being very powerful to as all the hard work has been done.

Being open source, some of the customers didn't like that idea. They would have preferred a paid for partner. The solution was the paid for Talend version with support, however the tag "open source" put some project sponsors off.
Apart from that there is nothing to really dislike Review collected by and hosted on G2.com.
