Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Axis by axis
Execution1 vs 1
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Library of Ruina
Turn-based card combat, no input precision.
Vampire Survivors
Movement is trivial; no aim or precision required.
Reads1 vs 0
Library of Ruina leans a little harder on reads, though the gap is small.
Library of Ruina
Scripted enemy decks, no adaptive opponent.
Vampire Survivors
Enemies follow fixed spawn scripts; no adaptive opponent.

Library of Ruina leans a little harder on variance, though the gap is small.
Library of Ruina
Dice rolls and draws swing fights moderately.
Vampire Survivors
Level-up offerings and pickup drops are randomized.
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Library of Ruina
Deck construction and clash math is deeply solvable.
Vampire Survivors
Evolution paths and weapon combinations fully solve the run.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
