BIGTREETECH SKR V1.4 TURBO or MINI E3??

hi, im looking to upgrade the mainboard on my Ender 3 was pretty set on going with an SKR V1.4 Turbo with TMC2209 drivers, and then i came across the Mini E3 with integrated drivers.
does anyone have an opinion on which would be better suited?
i like moding things out so some room for improvements/upgrades would be good.
the E3 processor runs at 72 MHz as apposed to the 1.4Ts 120 MHz does this make a noticable difference in performance? i assume it must.
so what would you choose if you were in my shoes haha?
any info/opinions would be greatly appreciated.
cheers,
josh.
