I run the iron banner helmet, imo it looks good with everything. The trials helmet looks good with some setups, but the mouth piece clashes with almost every shader imo. The only other one that looks relatively decent is the new monarchy one, but again, only with the right setup. This is all just my opinion anyways, but I figure that I would put my 2 glimmer in because I've been a titan "main" since tdb. (I love and play all of my characters, and do almost equally, but at the end of the day I always go back to titan lol)
