NL or Trainwreck

I'm thinking about growing Northern Lights, or maybe Trainwreck.

Which one would you go for? Differences?
Are the Northern Lights x Skunk ones any good?

Who do you think carries the best NL? (I'm looking to get fem. preferably, or maybe regular 10 seed pack if it's cheap enough)

Thanks

northern lights, the best?? id say sensi

Having grown NL many times and about 2 weeks to go on my Trainwreck- I'd say:

1. Sensi's NL is more uniform than GreenHouses Trainwreck. TW has alot of different pheno's, some 7 ft. tall, some 4.5 ft. One or two are monster trees!!! Also some TW done in 52 days, others look like 65-70 days.
2. NL has more more indica body buzz/ TW is all in the head.
3. Both are fairly low odor. I think TW produces a little more weight, due to bigger plants.
4. Both fairly easy to grow.....
