I like how easy it was to learn, use, implement and customize our system with what we needed at this time in construction industry today! No problems here so far as using esti 360 during my first month of implementation process (1 year ago). The only issue that i have now its about customization which takes some more effort but not much compared to all benefits you can get from implementing such software/tool available out there nowadays. If your looking into an integrated toolbox where everything works together then go ahead if thats really important because other tools are great too just compare them before making any decision whether or no to invest further. Planning project costs up front will save us alot money down the road when managing multiple projects simultaneously.
