Personally, I would try TaxAct over H&R Block.
I completely understand your disappointment with the discontinuation of ItsDeductible. However, as far as I know, other products like TaxAct, H&R Block, TaxSlayer, etc. don't have that feature either, so the discontinuation of that shouldn't be an automatic decision to leave TurboTax. You'll likely want to compare the core tax-product of each brand to determine which you want to use (as I mentioned before, personally, if I was using Do-It-Yourself software, I would try TaxAct before the other brands).
