90 Elmars are nice sharpe lenses if in good condition. Uncoated ones tend to be rougher and need maintenance compared to newer coated ones. You will need to stop to 5.6 to get critically sharp pics.
Cmpared to modern lenses, they lack microcontrast so fine details like skin texture are not as prominent as with newer glass. Uncoated ones have less shadow detail and what is there is lower contrast. Over exposed highlights will block faster. I have done the test side by side and that is what I found.
The latest 90 4.0 images like the 90 AA Summicron.
So you have your choice on how you want the pic rendered.
