The Fringe actress told Digital Spy that UK television offers up "more diverse" roles for women.
"[In the UK] it's less based on how you look and more based on real women," she said. "It's less aspirational, if you like."
Brady added that American television puts a "lot more... pressure on women", but insisted that she enjoys "popping back and forth" between both countries.
"It's a very different experience working there and here," she said. "If people still want you on both sides of the Atlantic, then yeah."
The Irish actress has appeared in four episodes of Fox's Fringe since 2010.
"It's a very, very polished show... that moves along very efficiently," she explained. "You slot into a very, very well-oiled machine."
Brady will next been seen in ITV1's Eternal Law, beginning on Thursday, January 5 at 9pm.
