Compare different Chest Slots

I want to compare the Items in two different Slots. 
My way is:
1: get the data from Slot A (save it in a Storage)
2. Remove the Count data (because i only want to check If it is the same Item)
3. Get the data from Slot B (save in storage)
4. Remove 
5. Compare both storage and If it is the same Trigger a Scoreboard
Is there a smarter way to compare this?
Because i have to compare a lot.
