Do you all write up the metal flexible conduits as a defect? I didn't see any deficiencies with the conduit itself...

As a defect NO.
I write them up as subject to rust and should be upgraded to a weather-tight material. Some may call it Seal-tight material.

Flexible Metal Conduit is no longer permitted for use in wet locations. (2008 NEC 348.12 )
When it was allowed, the conductors inside it needed to rated for wet locations also.
As a defect NO.

The technical and correct term is Liquidtight flexible metal conduit (LFMC) or
Liquidtight flexible nonmetallic conduit ( LFNC)
Sealtight is a brand of LFMC like romex is a brand of NM cable.
( but everyone calls it sealtight and romex , just like band-aid and kleenex)
