That is a difficult question to answer, as it so depends on your taste and just which commercial wine you are comparing.
There are some $7.50 commercial wines at Costco that are really nice wines. At the same time, there are some $20 wines on which I wouldn't waste my money.
Kit wines are a bit thinner and the range of kits you named is not exactly a premium kit.
I know I will get some argument and I don't intend on stepping on anyone's toes. Realistically, but strictly in my opinion, if you make the kit exactly as is and don't use an oak barrel, you are looking at something comparable to about a $10 wine. If you move up into the ultra premium kits, they would compare more at about $16 to $18.
With tweaks and the use of an oak barrel for the reds, you can add a few dollars to each of those categories.
I don't know why I am even trying to answer; it is all very, very subjective!!!
