I don't care for either.
I like the Klingons minus the piercings.
I'm not picking on you, but I think this is part of the problem with some people and their relationship with Star Trek. Not every Klingon is a warrior, the franchise mostly treats them as such. Just because a couple a Abramsverse Klingons have piercings doesn't mean that every Klingon has piercings. Just like because 99% of Klingons we see are warriors, doesn't mean 99% of Klingons are warriors.
Some people just seem very uncomfortable with any variation from what they've come to expect.
As far as the Romulans, did the countdown comics before the movie came our depict Nero with tats?
Both with and without. It explained the tattoos as part of the Romulan grieving process.
