Yes, I am not disagreeing with you. Sony's mirrorless bodies are presently the best and the Sony GM lenses also have the best-in-class image quality, surpassing DSLR lenses. For example the Sony GM 135mm f/1.8 is the sharpest available 135mm lens [1] and the Sony GM 24mm f/1.4 is the sharpest available 24mm lens [2].

Sony's ecosystem also has many amazing third-party lenses. A personal favourite of mine is the Voigtlander Apo Lanthar 65mm f/2.
