I run both Olympus MFT and Nikon DX format cameras. I do love the Olympus gear - it's fun to use and with affordable lenses like the Voigtlander 10.5mm f/0.95 a hoot to use.

I do have issue with the dated sensors used by Olympus and they really do struggle in poor light which is why I now do most of my landscapes with a Nikon D7500 and Tokina 14-20mm f/2 zoom.

If shooting during the day or indoors in normal lighting, it is still hard to beat the Olympus OM-D E-M5 with the 12-40mm f/2.8 lens. It is unbeatable value for money, compact and light weight and if travelling light, still my pick.

The talk about depth of field isn't such an issue when there is affordable fast glass. It levels the playing field and also MFT cameras are ideal for macro work where the greater depth of field is a plus.
