From what I remember, the TRIM bugs were finally completely squashed in Android 4.3 (they were particularly severe for the Nexus 7 2012 because it had relatively slow internal storage). Assuming Samsung didn't reintroduce them somehow, the Note 3 (which launched with 4.3, IIRC) and newer should never have had any TRIM problems. Any Note 2 TRIM issues should have been fixed with the 4.3 update (which has been completely rolled out for some time, I think).
