It's better to just put in the time. Understand each character and what you're trying to boost and why.
Which characters rely primarily on speed? Which ones need less speed, but need a lot of potency or crit chance to use their skills optimally? Which ones need to stack maximum health and/or tenacity?
Then understand the difference and relative strengths between the set bonuses, primary stats, and secondary stats (both straight numbers & percentages).
Once you understand the needs of your characters and how mod stats work, you can view your mods and see which ones will "fit" best for characters.
I strongly disagree with several of the recommendations offered by CrouchingRancor, because they seem to be written algorithmically and not based on an understanding of the characters.
That's what the customization sliders are for, it's literally just a time saver. Hower it doesn't offer a option to prioritize sets that I can find so there is a big hole there.
