Question: Between Rooney and Lostprophets, which group has more members?

Context paragraphs:
Borderline (band): Borderline was an early-1970s band from Woodstock, New York, that fused elements of folk, rock, country and jazz.  Consisting of brothers David Gershen (b. 1947) and Jon Gershen (b. 1950) as well as Jim Rooney (b. 1938), the trio recorded two albums, the second of which was not officially released until 2001, and then only in Japan, due to record company problems.  Though the group did not enjoy a great deal of commercial success, it was part of the “Woodstock scene” of the early 1970s that included Van Morrison and the Band.  Borderline was a forerunner of musical artists who would eventually be grouped under the “Americana” genre.  Also notable is that their two albums featured some well-known backing musicians including members of the Band.  After Borderline broke up in 1974, the Gershen brothers pursued various projects while Rooney became a successful producer in Nashville, working with artists including Iris DeMent, Nanci Griffith and John Prine.

Al Rooney: Albert "Al" Rooney (1892-?)  was an American gang leader and founder of the Fourteenth Street Gang.  One of the independent gangs allied with Monk Eastman, most of them former members of the Humpty Jackson gang, Rooney led the group from the mid-to late 1900s (decade) until the New York City Police Department launched a four-year citywide campaign to break up the countless street gangs operating in the city between 1910 and 1914.  Rooney was one of the first gang leaders to be imprisoned and, with his conviction of second degree murder in 1911, is considered one of the last generation gang captains of the "Gangs of New York" period.

Lostprophets: Lostprophets were a Welsh rock band from Pontypridd, Wales formed in 1997.  Founded by lead vocalist and lyricist Ian Watkins, bassist (later guitarist) Mike Lewis, drummer Mike Chiplin and guitarist Lee Gaze, they were originally a side-project to hardcore punk band Public Disturbance.  They were also part of the Cardiff music scene.

Rooney (band): Rooney is the primary musical project of singer-songwriter Robert Schwartzman, evolving from its origin as an American rock band formed by high school friends in Los Angeles.

The band is named after Ed Rooney, the principal in "Ferris Bueller's Day Off".

Geoff Rickly: Geoffrey William "Geoff" Rickly (born March 8, 1979) is an American musician, best known as the lead singer and songwriter of rock band Thursday.
