Does using BPEL considered to be a disadvantige when searching for an open source tool
===

I am searching for an open source tool for building an automatic workflow , and i found a tool named "Intalio|BPM" . It contains most of the features which i need and it has lot of success stories. but the only thing i am afraid of is that the tool will design the business process based on Apache ODE BPEL, while other open source tools will provide a REST API to interact with instead of BPEL.

So does using BPEL in an open source solution should be considered as a disadvantage compared with other tools that uses REST API?
