Power Regulators on BoE & SC

Hi,
I am producing my own PCB, copying some of the circuitry from the Board of Education, and Super Carrier (SC) Boards.
I am now doing the voltage regulation circuit, and I see the BoE and SC differ somewhat.
The BoE uses a single 1000uF Cap (C2) between Vss and Vdd
where as the SuperCarrier board uses two Caps, a 47uF (C1) and a 1.0uF (C2) between Vss and
Vin or Vdd respectively.
I was going to reproduce the circuit from the SuperCarrier board. But all my prototyping was done
on the BoE. So my question is: Is there any major difference between the two? Is there any reason
I should follow the BoE design instead of the SC ? My circuit will drive a servo, but this will be connected
to Vin, and not Vdd - so I don't think it has any bearing on this.
Your advice is appreciated.
