Like everyone else said, exterior definetly the way to go if you can.
I will add another consideration however. When I lived in Calgary, weeping tile was not mandated by code. As luck would have it, our place had weeping tile but it was not drained into a culvert, storm sewer or some other form of natural sloping to get the water away from the house properly. this limited the amount of water it could handle and with Calgary being much wetter than it was 10 years ago, this could present a problem.
If you already have weeping tile you may be able to solve your problem like we did by installing a sump pit. Dig a sump pit at the low end of the basement, go under the exterior wall to tie into the existing weeping tile. Install the sump pump and an alarm and vent the sump outside and away from the house.
