The best thing I like about this tool was that it has very easy to use interface which makes my work faster than others. Also its free version available with limited features are good too but you should pay little bit extra if your requirement high then go ahead otherwise there can be some issues in case of using free versions. And lastly this software have all those tools integrated so i am able to perform multiple task at once without having separate softwares or other applications installed separately on system because everything comes under one roof. If u r looking out new ways by developing application fast way then virtuso will help you lot from development point of view also when we compare speed between two programs sometimes due to integration issue performance gets affected.
