I use peak 50/50 blue European with no issues
Pros: no issues
I used the Peak coolant that was pink, it's been a few weeks and no catastrophe so I think you are fine.
Pros: no catastrophe, works fine

I run the prestone green coolant in my e36 since 2006 and my 540i/6 since 2008. They're both fine. The old engine still looked & ran great. The radiator in my 540i was still from 1998 until very recently when I did a cooling system refresh - entirely preventive.
Pros: reliable performance, engine longevity

I stopped having to wear gloves when we stopped using blaser coolant. That shit gave me blister covered rashy skin that was unbearable for 2 years. All went away as soon as we switched to a cheaper Castrol coolant. Works about the same too.
Pros: cheaper, works about the same
Cons: blister covered rashy skin
Bmw original coolant is the only way to go. I made the mistake of using shell coolant once and it froze, causing a hole in my radiator.
Cons: froze, caused radiator damage
