done gearing drg, should i go for war or sch?

i really enjoy both jobs. i like that war and drg share right side so potentially fewer tomes to gear, but sch is also so fun and can carry fights by themselves.
any suggestions??

also if i chose sch should i switch my stats to mnd for better healing but gimp my smn or keep it int?

Depends. Would you rather tank or heal next?
I'm biased since I love SCH and I hate tanking in general but that's just me.

Also about SCH, do you use SMN at all? I keep my SCH mind-spec'd since I rarely use my SMN, and never for anything serious.
