It's hard to compare them in terms of IB teaching.
As far as I know, LA (宏信) is only an IB's interested school and it has a long way to go to become an authorized IB school. Whether LA will become an IB school is still in question because there are a number of schools (even the "elite" schools) having difficulties in implementing IB programmes. Some of them have to either postpone the plan or stay put.
