I usually make my way to Terminal E, Galaxy lounge. I found this to be the best SU lounge.

It is quite spacious, and you can look at the Aeroexpress station - yes, this one has a window. Normally it is also less crowded than the lounges in D or F, I guess simply because most flights start from there.

I got asked to go to a different lounge, but I replied I like this lounge the most and will start on-time for my gate, and they let me pass. Just the Sky Priority label or print on the boarding pass they usually do not accept, you have to show them your Skyteam card.

Food is average, Choice of drinks is ok.
