All that I can tell you is that there's a reason why Critical Hitter has such a nasty penalty on the positive value, and that's because it has a 20% chance of making your fighter's attacks deal 3x more damage than normal. That can potentially lead to instant 1-hit KOs if you use a highly damaging attack. Whereas, Hard Braker's bonus effect only increases your fighter's traction, so its penalty on the positive value is quite small when compared to most other positive bonus effects.
Anyway, while using the negative bonus effect equipment may seem tempting with their weaker stat drop values, be very aware that some of those negative effects may be very atrocious to your fighter. Hasty Edge and Meanderer are quite minor as a whole, but Anchor Jump and Double-Jump Drag can lead to your own undoing if you're not careful.
Some toughts on it I forgot to bring up:
My Greninja uses Perfect Shield- Speed X (I rarely shield anyway, Greninja is donuted on shield due to that laggy grab), Item Throw- Defense X (lol), and Crash Lander Attack X (his landing lag is either too low to matter even with the badge or too high anyway even without it, in the case of down-air). Being capable of keeping up with Sonic, hitting like a truck with much less ending lag, having the DI survivability increased from already unusual lenghts to absolutely ridiculous percents, and being able to damage himself by crossing the upper blast zone with only his double jump alone for a little laugh every now and then, and to destroy the pac-man ladder while I'm at it, is totally worth it.
Critical Hitter sounds like the reason equipement is banned... That sounds basically to work as a Judge for any attack, if luck strikes, GG. Still, Defense Trade and Full Trade suck, and that goes without question...
Mobility hampering equipement are the ones i throw to the trash directly. I rely too much on Greninja's speed for my own good, guilty pleasure. And I agree, hampering Corrin's already bad recovery is just plain suicidal.
Recently i got a Air Attack- sword for my Corrin. Due to having a +85 attack boost, i never see the drop to matter much, when compared to my regular Legend Sword...
I find Risky Respawner overrated. The 2 second invincibility comes in really handy to finish off somebody that KOed you at 120% or so, or simply to approach safely for a start-up combo. Perfect Shield-, on the other hand, considering in general you are better off dodging, or using a counter if you have one, than trying to go for a powershield...

I think that means the max positive stat is +90, but it translates to +85 maximum benefit when taking into account the -5 negative on the other stat
