"As far as Flores versus Murphy defensively, I don’t think there’s any guarantee that the youngster will be better. There’s a small split in the defensive metric with respect to Murphy’s 2012 season: Total Zone Rating has him one run below average, BIS Defensive Runs Saved has him +1 and UZR has him nine runs below average. I really think Murphy is quicker than Flores. The Irish Hammer stole 14 bases in his last full minor league season in 2008 in 99 games. Flores has 14 stolen bases in 589 minor league games through his age 20/21 season. The nicest thing I heard about Flores’ work at second in 2012 was that he was still “learning” the position."
"Flores at second is more appealing than in leftfield, but I still think that it would be a stretch. He is, and will always be, a second baseman with below average range. Again, he’ll field the grounders he can reach, but he will not reach enough of them. He has good hands and a plus arm, but his feet are slow, too slow for short, and too slow to play an average second base."

"no one has actually said "flores is worse than murphy" and i would challenge you to find one person that has"
I am someone, I'm pretty sure. Anyway, there's a slight review of this exact discussion from Toby Hyde (posted above).
Not sure where you get those things and how you define each is better, seem more like assumptions, but BA had this to say on Flores in their hot sheet: " but not nearly enough range to profile at second." Toby Hyde agrees, "Flores just does not have the feet to have the range necessary to play second in the big leagues." So, you even admit Murphy has the better range. Using your own list, range is important, Murphy wins, Flores doesn't even qualify. We know Flores is slower (see Cooper's assessment: "He’s a 20 runner on the 20-80 scouting scale") and not light on his feet (heavy feet severely limit his range), so heck, so he's hurt even more there. On arm - we're discussing second base. If he wins the arms race, big deal, you only lose there since again, it's second base.
Some more:
Goldstein:
"Finally off of shortstop, Flores has split time between second base, where he just doesn’t have the athleticism to play"
(And Hyde's comment on Goldstein's: "I think Goldstein is on point regarding the idea of “Wilmer Flores, second baseman.” I still have not talked to a scout who thinks he will have the range to play there in the big leagues.")
And it goes on from there. What we have is a player that no one really believes can play second base, that has a good arm but can't do much else, so that leaves him at third, where he's still not good, and if he fails there then at first. The Mets are locked up at each, so if he moves up to Las Vegas, hits, and should do both of those, he's great trade bait - what he should be.
So by the non-belief in all evaluators in Flores' "talents" at second, and the belief that some think Murphy can survive there and get better (see has played there at the MLB level), I'm confident in saying Murphy > Flores's defensive value at second base.
