I don't think it'll make any difference to receive BTC using either wallets. If you wish not to be linked to the addresses, your best bet is to install a 3rd wallet client or create an online account just to receive the coins. You can use addresses generated by the 3rd wallet for inbound transactions only.
What's the best online account to use?
blockchain.info, you can add a mixer for more privacy but you will not get 100% anon
a good strategy for a good anonimity, would be to start with an amount that is already splitted among many adresses
then you proceed with the usual ramification
And blockchain.info has a built-in mixer-esque utility called SharedCoin (or maybe it's SharedSend, I get them mixed up).
