Eclipse - I did some side by side testing with the FKM and the DP 210 Gyutos. I just preferred the feel of the DP. The 210 FKM was thinner and lighter and almost felt too light to me. Part of that is the Western handle and the balance point on the FKM just made the blade feel too light for my taste. It's probably because I'm very used to Wa handles and balance points that are more blade heavy.
The FKM steel is a little more forgiving, being slightly softer than the DP VG-10 core steel. I do like the tip on the FKM better - it's a little more pointy and great for finer work like mincing small shallots and garlic, etc.
If you get the FKM, since they're a la carte - no sets, you might want to think about the 240 version of their Gyuto. I think it has a better all around feel than the FKM 210 and it's a taller blade as well - just a great profile.
I'm going to reiterate this, but the Tojiro DP's normally have slightly larger handles than the equivalent FKM models. If you have large hands, the Tojiro DP 210 might feel better than the FKM 210. Once you get to the FKM 240, the handle is larger, and better for a variety of hand sizes.
My wife uses the DP 210 and has very small hands - she has had no complaints on the handle, so it's not big - the FKM 210 handle is just a little more slender. F&F on both lines is very good IMO. After handling multiple knives from each maker, it don't think one has an edge on F&F over the other.
Here's a comparison video I did of the FKM and DP 210 Gyutos: http://youtu.be/wu5UzzBvARM
