I've found the Dunlops that I've tried to be quite similar to Wilson grips in their size and profile. As for Yonex, I have a pair of RDS 002 Tours and their grips aren't as wide and flat as my LM Prestige mids - I'd say that they feel more like a Wilson grip that's a little bit wider. By that, I mean that the wide faces of the grip (the ones at 12 and 6 o'clock as you look at the "W" on the buttcap) seem a just a bit more broad and I have the feeling a more oblong oval in my hand with the Yonex. While this shape is comfortable for me, the Head grip shape is rather distracting.
Some folks knock the Yonex grips for being comparatively smaller than other grips, but it seems that the issue comes from the thin replacement grips that are supplied on their frames off the rack. I have rather thin Prince overgrips on top of the originals on my 002's and they feel more substantial than my old Wilson Prostaffs that are the same 4 5/8" size with the same overgrips.
