DCS : Difference between yokogawa and honeywell

Hello everyone, just for an advice, we are about to do a migration and i want to know what's the difference between YOKOGAWA CENTUM CS3000 and HONEYWELL EXPERION PKS and which one is better than the other.
Thank You.
I have worked with both. Both Yokogawa and Honeywell are good systems and they can do whatever you need, with some small differences. CS3000 is the old Yokogawa system, now it is CentumVP. I think I slightly prefer Honeywell, a bit more user friendly, but I would never base my decision on this. I would choose rather based on customer support, personnel and services availability and pricing in your region. Since any would suffice, quality labor availability and support in the long-term would be the most important, IMO.
