Hi Kesavan, You have a daunting task ahead of you. I use both tools and my preference is Expedition. However, I have been using Expedition far longer than Allegro. I find Allegro requires a bit more âmanualâ intervention (could be related to my experience level) to complete a design and Expedition is a bit more âautomatedâ (again could be related to my experience level). You can get the job done with either tool. Currently, I can work more efficiently in Expedition. Your decision might be better based on cost and/or familiarity if you have been using either tool. Regarding costs, you need to be aware of how each tool breaks down into their respective licenses. The trend over the last several years has been to segregate functionality into separate sub-applications within the major application tool sets creating an array of cost options. Life is complicated. As far as familiarity goes, I expect that if my time of experience with both tools were reversed, I would prefer Allegro.
