The free demo of Native is a very effective promotion move, I bought my LT three days after playing with the Native too.
Before the purchase, I was considering between Helix and AX8, and was leaning towards AX8, but after all it all depends on what sound you really want.
What is good about the free trial is you can see if it gives you the sound you want.
Unlike going to a music store, you have 15 days to play with it, dig into every parameter and see how they work, and see if you like the dynamics when you play with the amp/cabs.
Once i knew it gives me the sounds I want, it is a easy choice for Helix/LT's price, and you have the best UI you can have on any Multi/Amp Sim unit.
When you know what you want, you don't need take much care on what others say. And it is the Internet, haters hate.
