I found a 2015 Tsunami 120 for a good price. Any reason I should pass and get a new 2018 Tsunami (I know they did some model changes - storage and something about more above water clearance).

Any reason I shouldn't get the 2015 model? Or is the 2018 model noticeably better and definitely the recommended option, even considering price differences?

Leaning toward the 2015 unless you guys think the 2018 is worth the price differences.
