4131 vs 4130

[02acs]

Hope everyone is having a good weekend. I’ve looked online but wasn’t able to find a good comparison btw the 4130 and 4131 movements anywhere. I can find what the actual differences are, but not anyone saying if they realistically think the 4131 would offer any practical advantages in the long run. Talking mechanically, not the aesthetic changes. Since I practically won’t get one from a dealer anytime in the next decade, looking online and wondering if it makes sense to spend a little more for the newer movement, assuming I take the plunge.
Thanks so much!
