Current road bike (55 cm Klein Quantum) has a 55.7 cm top tube. Debating between new CX bike and have choice of 55 or 56 cm top tube. Better to be 0.3 bigger or 0.7 cm smaller? Note, I am 5' 10" tall.

Depends on Road stem length. if you are running a 120 then yes go long and get a shorter cx stem. You want your 'functional' TT length (TT and Stem) to be just a tad shorter (IMHO) so if you are running a 120 negative stem a 110 pos. on a longer TT would be good. Make sure bigger frame has good standover

I think a 10 or 11 should be the max stem on a cross bike,(assuming a 72.5-73 head angle)so use that as a reference.You may want the total reach to be 1/2 to 1 cm shorter.I try to have the same reach as my road bike,but most prefer shorter.

agree with 10-11 and I do like just a tad shorter than Road as I stretch on my roadie. Being that stretched in cx would be uncomfortable, plus use cx to commute, keeps me more upright.
