Gloucester and Harlequin Rugby Club are two professional rugby union teams from the United Kingdom competing in the English Premiership.
In terms of recent form, both teams have had their struggles. Gloucester has been near the bottom of the Premiership table in the past couple of seasons, while Harlequins have had some mixed results and finished mid-table in the 2020-2021 season.

Gloucester has a strong tradition and has produced many top-quality players, including England internationals such as Jonny May and Danny Cipriani. However, they have been rebuilding their squad recently and have struggled to find consistency.
Meanwhile, Harlequins has a talented squad that includes several England internationals, such as Marcus Smith and Joe Marler. They are known for their attacking style and have a strong record in cup competitions, including winning the Premiership in the 2011-2012 season.
Regarding head-to-head matchups, it’s difficult to predict who would come out on top without knowing more details about the specific matchup. However, based on overall squad strength and recent form, Harlequins would likely be considered the stronger team.
