Yes, I just found this post by @danda that explains the decision:

Our goal is (and has been) to make the most fungible and efficient token that we can. As such, we have looked at and experimented with any technology that is promising in that direction including blind signatures, ring signatures, and even (a little bit) zk-snarks. Blind signatures are neat because they offer provable unlinkability. Unfortunately they require the use of denominations, which expose the transaction amounts, make the anonymity set smaller, and require many more DBCs (and network…

Seems that blind sigs needed denominations and the latter had high overhead for the network and exposed transaction amounts. I’m still curious for more specific details, but perhaps there isn’t any as it was mostly theoretical work (no working models to compare).

edit: Also found this regarding denominations which I found interesting:

It is therefore important to keep the total number of denominations small. One could for example define every integer value to its own denomination. While this would work technically, it is bad for privacy, as people will often use very unique amounts. Instead of merging into an ocean, a single drop wanders by itself.
