CRT X1 CENTER DIFF 62t VS. 46T ???

Hey guys ,i'm working on my truggy conversion and was woundering if there are any pro's or con's with running either the stock 62t or switching to the Kyosho 46t center diff gear ??...i have both so i was just curious which the better option would be and why ??..i'm running the stock front and rear diff gears now ...but eventually will do the hot bodies LST ring and pinion conversion. Thanks for any info or advise on this (neu 1515 2.5 w/MMM on 5s...if this info helps any )
