Are they the same grape in different sizes?

No. They are separate varieties, rather than small- and large-berried versions of one grape. Wine Grapes reports genetic evidence suggesting a parent–offspring relationship, with Petit Manseng the likely parent of Gros Manseng.

Is Petit Manseng always better?

Petit Manseng has a strong reputation for fine sweet wines, but that is not a reason to dismiss Gros Manseng. Producer, site, ripeness and winemaking matter. Gros Manseng can make characterful wines in its own right and contributes freshness and fruit to blends.

Which should you buy?

Choose the style before the variety. For a dry white, investigate Jurançon Sec and explicitly dry varietal wines. For concentrated sweetness, look at sweet Jurançon or Pacherenc du Vic-Bilh. In every case, check the actual blend and sweetness rather than relying on a grape stereotype.
