This one is a tough one for me but I do think I like the printed ones just a tad more. Like some had said already, it's fun to watch the print stretch out and get bigger and bigger. I used to hold them up near a light and have the print facing away from me so as the balloon got bigger and more translucent, I could see the printing stretch from the other side. Otherwise unless you're looking at yourself in a mirror or something, it's not really easy to see depending on the location of the printing on some balloons if you hold it so the printing is facing you.
Today I got some LOL Surprise printed balloons. They were only $0.24 because they were being clearanced out so I honestly didn't care what they were. Ever since having Covid, my lung capacity has been bad but I was shocked that it didn't hamper my ability to blow up balloons. Quite honestly, it didn't even take me long to bust just because of the excitement of not playing with balloons for a few number of years now. And of course it included my favorite balloon color, pink!
