We present a comprehensive study of an unbiased sample of 150 nearby (<z> =0.014) core-collapse supernova (CCSN) host galaxies drawn from the All-SkyAutomated Survey for Supernovae (ASAS-SN) for direct comparison to the nearestLGRB and SLSN hosts. We use public imaging surveys to gather multi-wavelengthphotometry for all CCSN host galaxies and fit their spectral energydistributions (SEDs) to derive stellar masses and integrated star formationrates. CCSNe populate galaxies across a wide range of stellar masses, from blueand compact dwarf galaxies to large spiral galaxies. We find 33(+4,-4) per centof CCSNe are in dwarf galaxies (M < 10^9 M_Sun) and 2(+2,-1) per cent are indwarf starburst galaxies (sSFR > 10^-8 yr^-1). We reanalyse low-redshift SLSNand LGRB hosts from the literature (out to $z<0.3$) in a homogeneous way andcompare against the CCSN host sample. The relative SLSN to CCSN supernova rateis increased in low-mass galaxies and at high specific star-formation rates.These parameters are strongly covariant and we cannot break the degeneracybetween them with our current sample, although there is some evidence that bothfactors may play a role. Larger unbiased samples of CCSNe from projects such asZTF and LSST will be needed to determine whether host-galaxy mass (a proxy formetallicity) or specific star-formation rate (a proxy for star-formationintensity and potential IMF variation) is more fundamental in driving thepreference for SLSNe and LGRBs in unusual galaxy environments.
