I didn't mean that B56 on SL is better than b54 on L. i meant that b56 AND Snow Leopard are better than b54 and Leopard. Which means that I think Snow Leopard is enough better than Leopard to make up for the difference in QS issues...
If you're new to SL, and knowing that you're clearly an applescripter, I'd suggest checking out the power of Automator services. It's possible you can create services accessible via your mouse's contextual menu to replace mouse triggers. If you're interested, you can check out some of the services I've made, including shortening URLS dialinng/smsing with Google Voice clipping text to Evernote, Notational Velocity, and TextMate sending urls to instapaper at my tumblr http://elasticthreads.tumblr.com/
