There probably aren't many people around who have tried all of these compounds, which is why you're not getting any responses.
I've tried 11-sterone (11-oxo clone) at various doses between 450 and 600 over 6 weeks (4 weeks at 450 and 2 weeks at 600) and can't really say I got anything really noticeable from it except some lethargy for the last 2 weeks when taking 600. I'm going to be starting 11-KT on Sunday for my post-Xmas-splurge cut so I'll let you know how that goes. There are a few logs on PHF and 11-KT seems to kick-in a lot quicker than 11-oxo so hopefully I'll get something from it.
225-300mg 11-oxo is about the bare minimum needed and this is more for a cut rather than a lean bulk. You would need to up the dosage to 450-600mg to use for a lean bulk, which adds to the cost.
If you use 11-oxo or 11-KT you can get away without any type of PCT unless you run them for 8 weeks or so and even then some DAA/Erase would be more than enough to recover. For Androlean you will probably need a light PCT regardless of the dosage/length and if you use 6 caps per day for 6-8 weeks then you're going definitely going to need something for PCT although a SERM still wouldn't be needed. Check the PP sub-forums are there are some threads showing the results from people who have used Androlean and also a few logs.
