out of the ones listed, io would have to go with origional haze(purple haze is just a rare phenotype)
its potency is just out of hand, and that sativa high can be very very nice
but, if i had to choose just 1 strain, probably trainwreck
get the best of both highs
sativa head high for an hour or 2 int he beginning, indica body stone for the rest, gotta love it
