OEM or aftermarket lead acid replacement?

2018 M3, I want to replace the low voltage battery as it’s been several years. Should I buy a replacement from Tesla or has anyone had good luck with an aftermarket brand? If so which one? I’m not interested in upgrading to AGM. I tried searching posts but didn’t see anything super recent addressing specifically this.

The Tesla replacement is the best and also the cheapest.

Heck, Mobile service came out and changed mine for $109. Cant beat that.
