If you want the list to be a little less overwhelming, you can look in each rarity's section separately.

The better cards are obviously all R4 (but some R3 are so good that they compete with very crappy R4s).

Depending on what you are looking for, you can sort by descending ATK or descending "stats total".

Another important thing is to take each character's signature weapon into account (and whether you have it or not). Although most R3 weapons have almost identical stats (with a point or two being swapped around), R4 weapon can vary quite a bit more, both in total value of stats increase (ranges from 342% to 367% total, IIRC) and in which stats they increase the most.
