Inventory cleanup is easiest when you compare gear around the build you actually use instead of keeping every item because it might be useful later.
1. Keep the current loadout obvious
Separate the weapons and equipment you actively use from items that are only candidates for comparison.
2. Compare around your build, not one number
A higher stat is only useful if the item fits your play style and works with the rest of the setup.
3. Remove low-value clutter regularly
Sell or dismantle items that no longer have a realistic role so later comparisons stay fast.
4. Clean up between mission groups
A quick reset before the next set of jobs reduces hidden inventory pressure and makes new rewards easier to evaluate.
