I've been using the FJA4213 and FJA4313 to replace the 2SB688 and 2SD718

[bdgf2004]

when buying these should i get the R or the O? ( FJA4313OTU / FJA4313RTU ) the R has hfe - 55 @ 1A, 5V. the O has hfe - 80 @ 1A, 5V.

i think i should get the R it is closer to the original part spec.
not sure which one i should get.

It probably won't make a difference but if there is a choice, get the one that's closest to the original.
