I can’t think of many people at all who like the feel of the RGB since it’s made with flimsier materials in order to accommodate the lighting, but the feel of the R2 while improved in some ways over R1 (in my experience), is not much like HHKB, at least when comparing the silenced versions of both. The HHKB, being flexible and less solid than Realforce boards has a very different, lighter feel to it. However, you might enjoy an R2 silenced on its own; I personally sold my Type-S because the layout just was too inconvenient.
