BTC is currently bageling the last 2.5 hours which is equivalent to a 16.5 hour round so far here. ..
 
I find the break even point between the two is somewhere between 3 to 4 blocks.  If slush solves more than 4 blocks in a 24 hour period, its payout is greater than BTC-G. .   If its less than 4 blocks, then BTC-G pays more. .     BTC doesn't vary much over any 24 hour period because of its size, but slush can solve 2 blocks or 9 blocks.  So when its a large number of blocks, Slush wins big. .   but generally they are very close to each other in terms of payout performance.
