First, I love both of these names!
They are too matchy for me personally, but I don't think of a label. I'm just not a fan of the alliteration. But I don't side-eye other people for it, unless it gets really bad (like pp's Duggar reference). So I guess it comes down to whether the alliteration really bugs you, and whether you're planning to stop at two kids; if you have a 3rd, will you feel it needs to match? That would be too much for me, but it also might be a little odd to have two names that are so close and then a third name that isn't (although that would still be better than 3 matching ones, IMO!).
