Higher timing and more MHz or lower timing and less MHz?

Solution
Of those 1600/7 look at DRAM as stair steps to compare each step up in freq add 1 to the CL or (for performance sticks

1600/7 1866/8 2133/9 2400/10 2666/11 each step up is a slight increase in overall performance so if you throw in a set of 1866/9 that's a loss to the 8CL in the above steps (slower) or the 1600/7 would have a slight advantage

for example what's better
8GB G.Skill RipjawsX DDR3-1866 DIMM CL9 Dual Kit
PC3-14900U
CL9
RAS to CAS Delay (tRCD): 11
Ras Precharge Time (tRP): 9
Row Active Time (tRAS): 27
or
8GB G.Skill RipjawsX DDR3-1600 DIMM CL7 Dual Kit
PC3-12800U
CL7
RAS to CAS Delay (tRCD): 8
Ras Precharge Time (tRP): 8
Row Active Time (tRAS): 24
or
8GB G.Skill Ares DDR3-1600 DIMM CL9 Dual Kit
PC3-16000U
CL9
RAS to CAS Delay (tRCD): 9
Ras Precharge Time (tRP): 9
Row Active Time (tRAS): 20

for i5 4570, in future i'd like to swap it with an OC CPU
