It's easy for me when I want add new module or change existing one in my application using Eclipse integration toolkit which makes it so much easier than doing manual deployment at client side through web console mode! This product has really helped us reducing our development time by more then 50% compared from traditional approach without any issue related security vulnerability found during testing phase!! We have also no issues while deploying/releasing updates via eclipse plugin since this was fully supported out products like we are not required do anything custom work arounds anymore. Nothing dislike what i can think about but only because there nothing yet that need be fixed here :). For sure you should try if your organization still use same old tools where all things done manually including deployments before now just go ahead give them chance too enjoy benefits they get after few months trial period! There will come some improvement needs sometime may take longer periods sometimes even years until complete migration happen, best choice always make firstly look how fast does.
