Both sets of players have same advantage, defensive and offensive.
u can be defensive table tennis player and retrieve until UE. Kinda like tennis ruled by Nadal. Nowadays he overturn, tennis used to favour shotmakers.
Usually, among players with similar rating, the attacker will beat the defender more often than not, though at the semi-elite level there are a lot of guys with little offensive skill but serious touch who toy around with inconsistent attackers.
Personally, I hear this term all the time by commentators during matches, particularly after long, exhausting rallies. i.e. "WOW, that was like a ping pong rally!" usually during a monfils, simon, and even during Murray, Djokovic and Nadal matches, but pretty much any time when there is a rally longer than 15 shots. It wouldn't be so annoying if it weren't absolutely the antithesis of what table tennis point construction actually is. Commentators on any professional sport just look silly when they clearly know very little about another sport, especially one that has the name of their own sport in the other sport.
