Applications storing data in DAs is an ugly hack. Storing it in the Wimp Slot is much much much wiser, but unfeasible under ROL's OS. Plus, 32 bit gives us shared libraries. Obtaining the sources to ROL's OS to fix glaring bugs is much more difficult than the same for ROOL's. I would certainly choose RISC OS 5 over any recent Select; I favor simplicity, design pedigree (as little as RISC OS has) and proven stability over Sun Raster import in Paint, a bundle of new APIs no applications use, broken abstractions from the kernel, and badly-drawn curved buttons.
