The diff between between the banana split & rOarGe I'd say is the rOarGe exhibits more banana into it as far as flavors, but grows like a stout OG although it does jump a lot on transition to flower. The rOarGe stays a darker green on the leaves til the end and has a darker green hue with a tint towards blue on the leaves while BSOG will yellow up good on the leaves and retains an army green/kelly green throughout veg and most of flower.
The BSOG tastes more like OG than rOarGe but I think BSOG is tastier than most OG's. it has a cool, extra lemony, slight fruity tinge that accompanies the classic og flavs. The BSOG passes for more of a straight OG than rOarGe. rOarGe has more of a vibrant orange hair when ripe and retains some blue colors in the nugs where the BSOG is more golden almost. Both ripen about same timeframes although one could pick the BSOG before the rOarGe since the rOarGe is a major 4th quarter comeback queen, she does a lot of work the last 3 weeks and just ripens up instantly the last week. She looks way diff at the end of flower than mid, she gets super dank at end.
I could go on, but I think that covers most of it.
The Lizard King...is the Lizard King...lol Tastiest OGbrid I've had, can pass as straight OG almost but a pro will know it's a hybrid but they will love the new flavors that it throws out. Overall the taste best question is best answered with one word: subjective.
I like all three, prob would take the LKOG for overall tastiest, but that's me, one of my good buddies is rOarGe all the way!! lol And another is actually BSOG...It's all the person is growing now practically.
I got a new idea for a new path for the Lizard King OG...gonna create a hybrid with it, it's gonna be awhile but I'll keep you in mind to test it. The Blue Bus will make it end of 2012 hopefully...
