I'm doing a comparison grow of those strains to illustrate the difference in genetics on another forum.
You can check that thread
here.
I'm not finished and it didn't get off to the start I'd planned for so I ran 3 El Nino the first time then 5 La Nina and one El Nino clone the second time. I'm @ 30 days 12/12 with the La Nina right now.
The 2 strains are NOTHING alike, not at all.
There were no signs whatsoever of Haze influence or genetics in the El Nino. Only one of the 3 was worth growing. The other 2 were about as potent as the bag seed I grew when I first started. One of them threw 'nanners too.
Even though I did get one good plant, I'll never buy GHS again.
Though I've not yet tried it, this La Nina is gorgeous and very Sativa dominant. It smells like a skunk in veg, more odor in veg than the El Nino at full flower. I'd recommend this strain based on what I've seen so far provided you want a Sativa. This really does grow like a Sat so plan on 3x height gain in the stretch.
Gratitude
