The engine will be snappier with the shorter rods.
For engine speeds 6500 rpm and below, shorter rods and larger ports seem to be the ticket to best average torque. Check out the Enginemasters series.

If you go back in the archives you will see that I was as rabid a long rod guy as there was. However, over the last 10 years or so I have come to understand that longer rods aren't necessarily better for a street engine.
For another example, the chevy HT383 is built by chevrolet with a 3.80" stroke and 5.7" rods. That's a R/S ratio of 1.50. This engine passed all the durability tests,which were quite frightening as I recall. They found that at 7000 rpm after hours of running, the connecting rod bolt heads would fail, so they built a new rod specifically for the HT that uses a capscrew. There was enough room in the engine to put in a 5.85" rod or even a 6" rod, they had the L99 rod which is powder metallurgy like what they ended up with and 5.94" long. But they chose to use the 5.7" rod and 1.50 ratio.
