Best 1911-22 enhancement brand?

[LINEOFDEFENSE]

I've been searching online to try to find the most recommended enhancement package for the GSG 1911-22. I know it is here locally and they are at the top of my list so far however I wanted to double check. $10 savings isnt so much of an issue, but rather firsthand pros & cons. I am planning on replacing spring, guide rod, bushing, and eventually sites on both of our GSG 1911-22s.

Also, if anyone knows of a different dropin site replacement instead of Dawson, lmk. Thanks ingo!!
