The things that lacks the more regarding SCH vs BLM to SCH, and that you didn't pointed out, is
ga elemental spells. You can't get them via stratagem, and this is where blm can outdo sch. Except for this, i think sch solo better in almost every case than blm. Alot more mp regen helps alot, desert boots (yeah, not if you have herald gaiters, but, well, one is 20 M the other one 20k, and i personnaly can't afford, by far, the gaiters, so if you are in this case too, basically, your sch will have 12% more speed than your blm, which is just HUGE). No stun is not that limitating, and i think the mov speed make a much larger difference in term of safety. You also have a much much more better stoneskin as /rdm, same for phalanx (not that much important, but still). ALot more healing potency.
Anyway, problem of solo as blm will be mainly the lack of mp refresh. Sublimation does alot for that.
Hope it helped you ^^'
I personnally enjoy alot solo, and choose sch over blm
Edit : as for others things than soloing... meh. Blm is just an always wanted job, and sch is a rising star considering that ; not all LS seek massively for sch, but it is not uncommon to have people fight each other to get you in their own party when you come to an event ^^ fun. I would call them on par regarding this, but my point of view is biaised
