I think I'd agree with the OP, the eccentric is more precarious. Weakness on the pull and the bar slows/stops but there is still control, weakness on a slow lowering and the weight runs away from you breaking your form. When you are at 4+ plates then your strength on the day can be a little unpredictable and your 5 rep max can be lower than it was last week and you don't want to discover that in a precarious position.

It's like comparing driving up a steep hill vs. coasting down a hill with just the brake, a slight bump or misjudgement and things get hairy quick because gravity is compounding your mistakes.
