Use whichever DEF that you feel comfortable with. I think it was a coincidence that your AdBlue heater failed at the same time you switched brand. Many owners use other brands of DEF instead of AdBlue without any problem.

Not long after that, check engine warning light came up.. The dealership had to replace the AdBlue heater. The MB service advisor recommends only to buy their AdBlue. My question is the AdBlue’s equivalent DEF manufactured by the company in the US, bluesky.
