Which Wireless card has stronger signal: WMP300N or WUSB300N ?

I have been looking over the data sheets for these two Linksys wireless
802.11n Draft 2.0 cards, and am wondering if one has a better signal
strength range than the other?

WMP300N is the PCI version of the adapter and here is what is listed for it
from the SPEC sheet:

Transmitted Power 802.11g: 12±1dBm (Typical); Wireless-N: 10±1dBm (Typical)
Receive Sensitivity 54Mbps @ -70dBm (Typical); Wireless-N @ -70dBm (Typical)

----------------------------------------------------------
WUSB300N is the USB version of the adapter and here is what is listed for it
from the SPEC sheet:

RF Pwr (EIRP) in dBm 802.11b: 14±1dBm (Typical)
802.11g: 14±1dBm (Typical)
Wireless-N: 14±1dBm (Typical)

Receive Sensitivity in dBm 11Mbps @ -86dBm (Typical)
54Mbps @ -68dBm (Typical)
Wireless-N @ -62dBm (Typical)

----------------------------------------------------

So, is there any difference?
