I'm a little torn, I like them both... The 2015 still has the classic cruiser styling that sometimes fits in better with "cruiser" people... The 21 looks good too, In a different way... I've been wanting heated grips (that I installed on my 2015 after I bought my 21, I guess someone else will get to enjoy) ... Cruise control!!!! And overall feels smoother and better balanced... Haven't gotten used to forward controls yet. Feels weird...
