One of many useful features of LINQPad is the output visualizer ("Dump"). Granted, there are now NuGet packages (very likely inspired by LINQPad) that can do something similar in a console app but LINQPad is interactive, allows drill-down and can export to formats like Excel. It's such a productivity boost.
The database integration is also great and allows me to write ad-hoc SQL queries using LINQ.
