OEM or Aftermarket Windshield rubber?

[CG]

I have an NOS windshield rubber (no groove) that seems to be very nice. Not dry or cracked, feels new.

I also have a Precision window rubber.

I really don't care about originality here so I was thinking just go with the Precision rubber and pass the NOS one on to someone that is doing a resto.

Or would I avoid install problems by using the NOS? I feel like I have heard
good things about Precision.

Looking for opinions from folks that have gone through this.
