Yes, some of us have been around for awhile.
I've got an Estes Sweet Vee setting in my closet. It's apple and oranges, IMO. The Estes glider is pretty crude compared to something such as the UMX ASK-21. A mechanical mixer compared to something such as AS3X, for example. The wing span of the Sweet Vee is around twice the size of the ASK-21. Hi start or aerotow vs. rocket launch.
Check out the Sailplane section here and you can find better things to compare than the Estes rocket launched glider.
