I have used both of the major tax prep programs out there, and cant say that I find one that much better than the other. I like the way Turbo Tax presents the information. Thats why I use it. As far as installation goes, I had no problems. My computer works the same now as it did before. I am running this on a older P3-450 and havent had my computer slow down at all. I would definately reccomend this product. There are still some issues that frustrate me with updates, but overall the product was definately worth the money.
