A computer scientist and a biologist will give you two different religions on judging venues. Both are correct for their field. The trouble starts when you apply one field's metric to the other's venues.
- CORE measures conferences; CS publishes mainly at conferences, which is unusual - Impact factor and Scimago quartiles measure journals; that is everyone else's currency - Trust the one your audience uses: hiring committees read their own field's signals - Interdisciplinary work is strategic: which community do you want citing you for five years? - Both systems get gamed; treat any single number as a noisy signal and triangulate
VenueFit is free and compares both systems side by side: CORE tiers and Scimago quartiles for 329 venues.
