I had the same dilemma back an hour ago but I decided on +10% BC efficacy and the elemental immunity because 1 BC/spark is not worth 40 sp IMO. Plus, if you have a "spark blanket" in your squad, its enough (at least for the "blanket" and Sirius (EX skill). Elemental immunity is indeed useful; most final-game bosses* are dark element and the +10% BC efficacy is just an extra and to waste the remaining 10 SP. so, yeah go for the elem. imm. and BC efficacy one :)
