Compare ATLAS.ti with other products and judge for yourself:
Fact #24: Performance: It is easy for others to claim their software has similar features as ATLAS.ti--just don't ask about their actual performance rates, format support, astronomical load times, and frequent crashes. Test with real-life material, and you'll see the difference right away.
In my research I used ATLAS.ti extensively, to code a massive amount of quotation (about 106000). ATLAS.ti is the only software around that makes truly mixed quantitative and qualitative analysis possible.
