TaxSlayer is another option, but at first glance they may have transitioned to online-only.
Between those options, personally, I would go with TaxAct.
However, don't eliminate the option for a tax professional. Yes, they cost more, but in some circumstances they can give advice (and correctly prepare your tax return, which is hit-and-miss with DIY software like TurboTax) that can be worth a lifetime of tax preparation fees. For example, I encountered a several real-life situations where a tax professional's preparation and/or advice saved TENS of THOUSANDS of dollars over just following TurboTax's directions. Although that large of a difference is not common, it shows the advantages of a GOOD tax professional.
