I would try
ClassicWb If i were you it is far more stable and fast than all the others " exeption is AIAB that is quite good too" It can also run fast on a real amiga unlike amisys and amikit "need days of modification to work ok on a vanilla". If you only intend to use WINUAE go for AMIKIT "os3.9" or AIAB "os 3.x" . Personally i dot find sys any good at all .. Amikit is a great experience with a fast computer and Winuae.
