Most of the advantages of V-USB is cheaper and (since RS232 dies as a default interface on common computers) better supported (thanks to USB) of interconnection with computers.
Since V-USB just supports low-speed USB (1.1 Mbps) and since it is very CPU-intensive on the micro (means you won't be able to utilze full 1.1 Mbps), RS232 should be faster.
You will need external components like 5 capacitors and an MAX232 but (tanks to hardware UART support) I think you may be able to transmit with over 2Mbps.
Best regards
and what maximum baudrate is possible to achieve with v-usb? max rs232 baudrate is 115200bps and i would be happy if v-usb can be faster than this
