Keyword Pot works the best for me.
For discovering long tail keywords and their search volume, google keyword planner is the market leader, and most keyword research tools on the market get their data by scraping them, so in that regard, it's better to skip the intermediary and go to the source.
But google keyword planner will not tell you anything about how competitive a keyword is to rank it organically - beware that the competition column they provide refers to adwords competition and it has absolutely no correlation to organic seo competition.
To find out whether you can rank for a particular keyword or not, the industry standard is to analyze the top ten results in google that appear for your keyword and figure out whether they are easily beaten or not. There are other types of keyword research tools that provide this data for you, Ferzy Keyword Competitive Analysis in my signature is one of them, and it's free currently for a limited amount of searches if you want to give it a try.
