Abstract
This article deals with various kinds of quantitative results about the comparison between the normalized Hecke eigenvalues of two distinct Siegel cuspidal Hecke eigenforms for the full symplectic group of degree 2 which are not Saito-Kurokawa lifts. We also prove some simultaneous sign change results for their eigenvalues.
