Need simple comparison of TT Basic, Deluxe, Premier

TT pitches the merits of each version.  And for 20 yrs I have used the Basic disk version for rental properties, depreciation,  rehabs, buy/sell stocks, foreign income, foreign tax, etc and have found Basic just great.  No State tax return required in Texas.  The TT pitches for each version don't really distinguish why I would pay more for the fancier version when Basic does all that I need very easily.  Maybe the fancier version asks more questions for the less knowledgeable?   Anyone offer a more straightforward answer why pay more?
