Here's a table showing the overlap (and unique features) of both algs:
*QgsZonalStatistics alg* *Alternate alg* Count x x Sum x x Mean x x Median x x StDev x x Min x x Max x x Range x x Minority x Majority x Variety / Unique x x Variance (i.e. numpy.var) x Mode (I.e.scipy.stats.mode) x Two statistical outputs (variance and mode) aren't available in QgsZonalStatistics-based alg, while two outputs (minority and majority) are missing from the alternate alg. I'm not an intense user of zonal stats either, and I've always used the QgsZoneStatistics one.
