publications - When picking a journal for my research should I value the publisher's reputation over the journal's impact factor?

I'm in the process of selecting an appropriate journal for my article. I short-listed a few journals based on topic coverage, IF and speed of the review process.

I am confused: should I select a journal with higher IF (2.3) published by a non-reputable publisher (MDPI) or should I publish in a journal with low IF (1.2) published by a reputable publisher (IEEE)?

By reputation I mean the reputable publisher (IEEE) is specialized in my area of research and non reputable (MDPI) is an Open Access publisher.
