I wish people would stop comparing nitro to electric. I have both and I love both but trying to say one is better than the other is like arguing that a shotgun is better than a rifle. Yes theyre both guns but you can hardly compare one vs the other.
Thats not really a cut dry answer to me...I'm not sure I could classify one as "The Best" and if I was gonna pick one Id say converted LST2/XXL ;)
but I chose one that was on your list :D
