What was it like trying to beat Yukiko's Castle in one day in the original PS2 version?

I read before that the Avenger Knight and Shadow Yukiko were a lot harder in that version for various reasons (Shadow Yukiko knowing Mind Charge, Shadow Yukiko having no weaknesses, the Avenger Knight being way stronger and not having a standard weakness, etc.)

There were also no Skill Cards, Shuffle Time worked differently, and from what I read on the wiki, chests didn't reset unless you either left the TV World or went to a different dungeon before coming back.

I'm really interested in knowing if this was a big difference and what the experience was like if so.

Any answers are appreciated.

By the way, I'm so excited for P4R.
