Re: Proprietary versus Open source ETL tools
Having used a few open source and proprietary solutions, my advice would be to go for open source.
About the best company on the market, of course all of those you talk about are good. IMHO, I have a few favorites in the open source world.
I enjoy Talend Open Studio because the program has a well designed interface with technically advanced features, a good debugging team and a large community.
You can look at all of the features here:
