&lt;p&gt;When developers can run a focused comparison in seconds as part of their routine, they stay in the habit. When they face a 10-minute full-database compare once a week, they skip it and the first broken compare shows up in production.&lt;/p&gt;

&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;For us it helped to run comparisons automatically in CI on every schema change rather than waiting for someone to remember to run it manually before release. That way the check stays small and frequent instead of turning into a slow full-database diff nobody wants to kick off.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;For me, comparison speed starts affecting the workflow when a routine check takes long enough that developers stop running it after each meaningful schema change. I’d rather keep comparisons small and frequent, which makes SQL Compare sound like the better fit for SQL Server teams that want the check to remain part of everyday development.&lt;/p&gt;

Honest question before tooling: is the comparison slow, or are you just diffing the entire database every single time? Most of the pain vanishes when you scope the compare to the schemas or tables that actually change, instead of grinding through millions of rows nobody touched. On big databases the data comparison is the expensive part, schema diffing is quick either way. So are you comparing structure or content? If it&#39;s content on huge tables, no tool makes that instant, you make it fast by comparing less.
