Depending on the source, vegetables can either be considered nutritious, flavorless and/or totally useless if not fresh. There are also mixed opinions on frozen ones.
A Livestrong article points out that it's not always a matter of the vegetables being frozen. Part of the issue is the travel time from the fields to the grocery stores shelves that can be as long as two weeks, which causes them to lose their original nutrients.
There's also the matter of how long the vegetables are stored and frozen in grocery stores and your home. Purchasing frozen vegetables in stores, ignoring the expiration dates and dumping them at the bottom of your freezer isn't going to help matters anymore than buying these same goodies after their expiration dates directly from a cashier.
Is buying fresh vegetables the most efficient way to go?
Not necessarily. In a Men's Health story, details about vegetables being "flash frozen" (blasted by ultra-cooled air), which forms ice crystals too small to damage the plant’s cells and nutritional content, presents another side of the coin on fresh veggies and why some are better when frozen.
