Keyword discovery is much better for long tail phrases but for popular keywords they almost the same. Some people said that Wordtracker has the excellent GTrends tool that allows you to actually check how much google traffic keyword phrases got.
Based on my research, keyword discovery seems to be more accurate due to drawing information from more sources and more versatile. It has the most extensive keyword search database available on the market. Here are some of the more beneficial features of keyword discovery:
Related keywords - you will have the option to view synonyms, misspellings/typos, pluras and permutations.
Seasonal Search Trends- This is quite useful for any industries that get more business at certain times of the year.
Keyword Density - You can check the keyword density of any URL to ensue that your pages target your most important keywords effectively.
Domain Research Tool - It automatically checks if your target keywords are available to purchase.
Keyword List Management - You can easily add keywords to a project that can be exported.
Hope this helps.
