Four years ago when I started playing golf, I picked up very old balls (Balata types) and used it. It took me a while to figure out that the balls went about 15 - 20 yards short on drive. But the balls stick like glue around green. Still, I will take newer, cheaper balls any day over those old ones. I.e, I don't miss them at all.
Which discontinued balls do you miss the most? which do you use now? - Page 5

I sort of missed the seam on the Pro V1 when they went seamless. I used it to mark a line around my ball for putting, and even had a theory that the putter face impacting the seam was more consistent than impacting a random dimple.
Pretty sure (but not 100%) that my theory was BS because I roll the ball better now than I did back then.
But every now and then when I miss one that didn't look like it came off of the putter right it crosses my mind.
