I know everyone has their opinion, but for me it's not worth the extra $$ if you're a recreational fisherman vs a tournament/guide fisherman. If you're invested in tournament or guide fishing the extra $$ can easily be justified. I've fished with guides who have 12" and 16" screens. Here's the only difference in performance I've seen (for the record, I have a 9" screen and do wish I would have spent the extra $200 for the 10".), with my 9" screen I can easily tell now if the fish are big fish or small fish. This is pretty much all you need to differentiate if you're on legal fish or short fish. I can clearly see fish on structures and see their actions to my bait. With the 12" and 16" screens you can easily tell the difference between a 2 3/4 lb fish and a 3 lb fish. If I'm fishing a tournament this is critical to determine whether I come in first place or last place and take home a $10K check or a $500 check. If I'm just filling my cooler it's not worth the extra $$. I can catch a limit with a 9" screen just as easy and fast as I could with a 12" or larger screen. For me, I'd rather spend the extra $800 on more rods, reels, tackle, or accessories for my boat, or other toys. Although as stated, I wish I would have spent the extra $200 for the 10" screen, I can't say I would catch anymore fish. It's simply because it wasn't that much more. The price jump from 10" to 12" is significantly higher and has been since they came out with them. The spread seems to get bigger each year.
