  The Gamow-Teller response is astrophysically important for a number of
nuclides, particularly around iron. The random phase approximation (RPA) is an
efficient way to generate strength distributions. In order to better understand
both theoretical systematics and uncertainties, we compare the Gamow-Teller
strength distributions for a suite of nuclides and for a suite of interactions,
including semi-realistic interactions in the $1p$-$0f$ space with the RPA and a
separable multi-shell interaction in the quasi-particle RPA. We also compare
with experimental results for GT$_-$ on ${54}$Fe.
