FinFX or ATC Brokers?

I am choosing between FinFX new ECN Pro account (Min 10K) and ATC Brokers (Min 5K) for opening an account with 5-10K.

Started testing EURUSD spreads since yesterday. The spreads are really high, it is because of low liquidity I think.
Commission is not included (FinFX +0.7pips, ATC +0.8pips)

ATC
Average: 1.48pips
Max: 14.0pips
Min: 0.10pips
>2pips: 37%
1.5-2.0pips: 16%
1.0-1.4pips: 34%
<1.0pips: 13%

FinFX
Average: 1.36pips
Max: 9.7pips
Min: 0.10pips
>2pips: 34%
1.5-2.0pips: 18%
1.0-1.4pips: 28%
<1.0pips: 20%

FinFX has lower spread so far this week.

Can anyone tell me of any differencies in orderexecution speed, slippage, liquidity between the two?

Please give some feedback - positive and negative for helping me choose broker?

ATC is not ECN really it's FXCM raw price feed before markup they pull from their liquidity providers. could face more often slippage negative or positive depend on trade size.

ATC comission is 0.8 per trade ( 2 * 0.4 per side ) lower than FXCM raw spread 1 pip but they are their IB. Spread in EU is usually 0.6-0.8 but in NY close it should move up to 8 pips! thin trading can be incredible there.

& to summarize I studied FXCM raw spread VS FXCM standard it's almost same spread -0.8 pips ( if you add comission ).

So ATC is more lower spread while execution is almost the same as FXCM standard accounts over slippage.

FineFX is integral ECN feed same as:
