Some time ago, I had a pretty funny experience at a party, where a dude with a few "not-really-bad-but-not-really-good-either" tattoos himself were complimenting some of my tattoos.
I was wearing a t-shirt, so my arms were showing. One of my arms is a full colour sleeve done by Marija Ripley, which (in my opinion, at least) is a damn solid tattoo. The other arm is filled with a bunch of smaller black and grey traditional-ish tattoos done by a local artist when I just started getting tattooed. Those aren't bad tattoos either, but there is definately a difference in quality those two arms between.
Now the funny thing was, that the guy was really into those black and grey tattoos, and was like "yeah, that other arm is okay too, but THOSE grey ones are awesome".
That was really weird for me to respond to, because I feel totally opposite, but I guess peoples taste doesn't always compare to what objectively is the better tattoo quality-wise...
