Here's a list I made of SOME (not listing all) abilities ranked from great all the way down to nearly useless.
Great
Ink resistance up
Cold-blooded (sounds really bad from the description but it literally only lets you get tracked for 2.0 seconds which is insanely useful)
Ninja Squid (If you like camping)
Stealth Jump (makes it excessively easy to super jump safely)
Good
Bomb range up (good as main & decent as sub)
O.K.
Comeback (gives some boosts but not enough to have a significant effect)
Ink recovery up (this is good for sloshers though)
Opening Gambit
Bad
Special duration up (only good with 3 mains but ain't nobody got slots for that :/ )
Ink saver main
Last-ditch effort (gives 2 big boosts but may not come into effect during ranked)
Terrible
Quick Respawn (with 3 mains it only shortens it by 1 second)
Swim Speed up (even with the 1.3 update it still sucks)
Run Speed up (this is popular, but it only shortens an 11-second run with no mains or subs to 9 seconds with 2 mains)
Nearly useless
Tenacity (at max speed it takes you >40 seconds of doing no inking to charge and at lowest speed it takes you >2 minutes of no inking to charge)
Just remember that this is not a complete list, but I put some of the most common and popular abilities. Stay fresh!
