[Opinions] As a sister to twins, I agree....
My brothers didn't have a major issue with it, but people really did group them together all the time. Most people couldn't tell them apart.
For this reason, very matchy names on twins can wear out their welcome a little bit, much like being dressed in matching outfits. (Then people really, really can't tell you apart!)
I like Faith and Joy as a sibset, however. I'd just make 'matching' twin names a little more subtle.
