Dodge! No, wait... Chevy! Or Ford!
Same arguement. Go to the store, look at both unit displays and features side by side and buy the one that YOU are happy with.
I'm a Lowrance man, but I know many that love 'birds. Some have a hatred of the other brand they dont own anymore due to various reasons that affected them. Point is, don't base your decision on such a large purchase on the opinions of a half dozen or so people.
All the best,
