Everything about ISE is horrible compared to Vivado. (ISE supports XDL and Vivado doesn't. But other than that ISE is just horrible)
I've never used Vivado. When I started using Xilinx FPGAs I started w/ an old S3 board. And I don't have the extra 20GB for Vivado.
20 GB is only the download. It needs 35 GB to 45 GB when installed, depending on if you install the SDK or not.
