I say keep the full chapters.
If one chapter gets split up into 3+ parts, it gets me lost and I'd have to back track to what happened a few moments ago.
The artificial cliffhangers also ruins a chapter's momentum, unintentionally making readers pick apart a section of the chapter rather than reading it as a whole.
I'm also on the same boat with the kireicake effect.
If the chapters are long, I'm all down to read it in sections.
But small sample sizes get my hopes up and hurt my soul..
