just need some info from the experts

i instruct automotive at a college in canada . in my program we do gen 6 and 7accell ,holley and ebl tuning and it really works out good for the top students as now we do a lot of the local hotrod and specialty installs and tuning but now its time to upgrade to more current systems including diesels

efilive is 799. with 2 credits hp tuners is 650. less 20% = 520. with educational discount
i have never used either one and would like to know which one is more user freindly and would be more long term and maybe better for a learning enviroment as from what i see from reading is there very close but one is three hundred cheaper
