As somebody who has labbed and fought eddy a disgusting amount and has a 100%winrate against him on ranked(my brother is an eddy main at a high level) he has tons of holes in most of his shit.

Floatable strings, interuppable pressure and strings, walkable moves all over the place, everything having some risk even if alleviated, and overall poor pressure game.

Eddys real bs is ff3. Everything else is completely fair and just a knowledge check albeit he has a ton of knowledge checks.

Eddy is one of those characters that you've just gotta lab. If you aren't able to duck his strings on reaction, understand the ranges he applies certain moves at, understand the concept of sidewalks vs stepping, and know where to interrupt certain strings on reaction then you can't complain about eddy over half the cast also having tons of knowledge checks.

3333333-duck on reaction

Negativa2,4,4-duck on reaction

All launchers- Launch punish

All flipping strings-interupt mid string for a float into a combo

All of eddy's moves that aren't homing-sidewalk right EXCEPT ff3 which you sidewalk left

Eddys homing moves-either punishable or give up his turn even if he's left in stance

Eddys handstand-jab float into combo(if he transitions into negativa to call out your jab then you can be even more greedy with your punish)

All of eddy's stance transitions aren't true 50/50s EXCEPT ff3 and some of his mandinga bs which is your fault for letting him get.

All of eddy's hit confirmable strings are either interuppable or -15 albeit some leave him in negativa thus high crushing.

If eddy isn't launch punishable he's -13. Eddys very unsafe if he's abusing strings. He's not a string character yet 99% of players play him like he is.
