Maybe I'm jaded with what you could do in previous editions and that's why I don't think any of the feats are broken in 5th. Everyone points to Pun-Pun as the golden example of breaking something, but you didn't need to go nearly that far in optimization to make any unoptimized character irrelevant in 3.5. Join a few 4e campaigns and play a rebreather sorcerer, Mia, and a killswitch. Those will be examples of characters that are so good at their jobs that anyone else in that role will feel uneeded. By comparison, -5/+10 is negligible.
Now the counter is "less broken=/=not broken". If we are acting as though 5th is the only edition of DnD ever, and that there needs to be absolute balance between all feats, ASIs, classes, and subclasses, then sure there are a lot of broken things. But I don't view the game that way. There is never going to be perfect balance and what is considered "ok" in terms of power discrepancy is going to vary from person to person. I believe Battlemaster/Gloom Stalker with XBE and SS makes the best use of these particular feats, and if that is the most optimized archery in the game then I don't consider it broken.
