In watching Matt Gerry‘s latest tutorial on Triggers, he recommends only having 1 type of automation process throughout your org, whether that’s a trigger, a flow, a validation rule, etc.

In his YouTube video, he demonstrates some benchmark timings to show the performance gains when executing a validation rule using Apex versus a declarative approach.

He also mentioned it could be a controversial topic and maybe some would disagree.

It also could be a somewhat unrealistic approach, depending on how many hands are touching the org and where their respective skillsets lie.

An interesting thought, nonetheless.

Any opinion?
