shimano stradic ci4+ 1000fb

Was kind of sold on the Shimano Stradic Ci4+ 1000FB but then today I came across the Nasci 1000FB. Both have Coreprotect, Hagane gear, X-ship and more but the Nasci is half the price, which is very tempting... So is the Stradic Ci4 a better, albeit more expensive, choice or will the Nasci give...
