Excel Query vs data connection, Query much slower

I've been working on overhauling some reporting and really struggling to get a good/fast/easy to maintain setup. Currently I have a workbook with a fixed "Connection" (under queries & connections) to snowflake databases that can import about 66K rows of data in roughly 10 seconds.

Cannot use the connection in power query or data model as I need so I tried recreating it as a query, copy/pasted the connection string and command text from the connection into a Query so that I can more freely use it, but it goes from 10 seconds to refresh to 3-4 minutes to load the exact same 66K rows of data.

Is there something I'm missing?
