Yes -- the Ravens' uniforms are iconic at this point, but they're still ugly and only one notch better than some of the worst sets in the league. This seemed to be a common opinion on this board a few years ago.
This is going to sound totally galaxy-brained, but I really think the Titans' (ultimately disappointing) uniform-switch kind of tracks with the turnaround in perception on the Ravens' uniforms. Both uniforms were considered bottom-six or seven sets for years, that -- while possessing a lot of character and having highly distinctive color-schemes/numbers -- just weren't very attractive and screamed late-nineties. Yet when the Titans switched to an even worse uniform, most of us changed our opinion on the old Titans' threads and suddenly ranked their White & Columbia Blue variants as being way above average. (I would include myself in this grouping).
I kind of think people are scared that the same sort of downgrade would happen with Baltimore and that's why we have a lot of people ranking their set as like... a C+ tier set, instead of a D-tier set like before. And on some level, I get why people are scared because I personally can't even think of a team in recent history that has nailed a major uniform-change without pulling heavy inspiration from an already-great uniform history of theirs (Chargers, Browns, Bills, Vikings, Rams' "modern-throwback" alternate, and even the Bengals without that one stupid pair of pants all come to mind).
Yet, in an ideal world, I really do think the Ravens can do so much better. Their uniforms just kind of suck. This is heavily subjective, but I don't think they're like the Columbia-Blue Titans or even the current-day Broncos in terms of best late nineties-era uniforms. The less risk-averse side of me would love to potentially see a change here (for instance, I've seen concepts on this board for a pearlescent black-purple helmet that would be incredibly nice, IMO).
EDIT: ahhhhh yes, I'm referring to Brandon Moore's concept: https://www.bmcreative.net/ravens
