More like the poor cousin. For most of time the Terra and Fiesta brand twins were in the Fleetwood lineup, they were non-basement entry models competing with contempory non-slideout models in the Coachmen Mirada and Fourwinds Hurricane brands, lowest cost A gasser on the lightest GVWR chassis that would carry it. I don't think the dealers tried very hard to sell Terra and Fiesta.
Entry level basement model Southwind Storm, and notch above Bounder and Flair were more popular, more comparable to lowest cost Winnebago, Tiffen, and Damon models.
Of course, brand alignments change, models get upgraded when the market improves, new brands show up at the bottom when the market gets slow and price conscious, or old names get recycled.
