Have had both.
Both worked great and without issue.
APA was a few years back, so no side by side comparisons.
1 DBM stands out and above to me, that is KMW.
The rest of the Aluminum ones I have used worked great without issues.
CDI
PTG (m5, never tried their “stealth” and now they suck to bad to order from)
Badger
Hawkins
Surgeon
APA.
The KMW and Terry Cross are a step above IMO.
