Which exchange/venue do you consider the most accurate value of BTC/USD?

Normally, the exchange with the most volume and liquidity would be considered the most accurate.  However, since Mt.Gox USD cannot be withdrawn and has a default risk priced in, this has caused huge distortions in the BTC/USD market and made arbing away this discrepanc very difficult. It seems many people no longer consider Mt. Gox the "gold standard" despite its volume leadership.  What exchange do you look at to value your BTC in USD terms?

Coinbase cause I use them to buy and sell the coins. The value of something is the price it sells at after all.

Very valid point, even though coinbase is not technically an exchange since it buys the coins from exchanges and sells them to its users.  It seems to do this based on a volume weighted average of bitstamp, mtgox, campbx and btc-e.  It seems lately they have changed their formula to decrease mt. gox's influence in this averaging. 

Coinbase also has the highest trading fee at 1%.  Where it wins is its liquidity and bank transfer fees only 15 cents (versus $40 for overseas wire transfers)

Bitstamp seems to be winning.

How far the mighty have fallen (Mt Gox).  It basically overvalued since ppl are forced to buy up bitcoins trapped there to sell them at other exchanges to get their fiat out.  Once all the big players have gotten their coins out that way, mt gox may actually be trading at a discount.

It seems Bitstamp is the new Mt. Gox in most people's eyes now.  I hope they have done a better job complying with US AML laws and registered as a MTB in the US states.  At the very least, I hope they are keeping very little funds in any US bank which are subject to seizure.

Coin base im my opinion! Not only is the layout great but there are heaps are different currencies and prices are very accurate!

It sucks though they essentially ended instant bitcoins though (limited now to only 10BTC a week from 50BTC a day).
