Oil sump spacer vs larger sump

[350_Jer]

Are there any benefits or downsides to running a larger sump such as the Stillen or Greddy, to running a spacer for the standard sump? I'd guess the fact that the actual sump is bigger (and aluminium) would help with cooling, and also only 1 gasket surface to potentially leak rather than one each side of a spacer? I already have a spacer kit but thinking of selling that and going for the larger sump. Cheers

I've got a spacer on my one, as we as a 19 row cooler/thermostat. 

I only got these for piece of mind on track, so if you're doing that too, both are worth it. 

I think the greddy sump is baffled iirc
