I have struggled to find any literature on this topic and wondered whether this made sense to anyone else...

would you say a diethyl sulfonamide group is better a leaving group then a phenylsulfonate ester?

...i thought that because the ejected phenoxide anion is stabilized through resonance and the diethylamine anion is destabilised via inductive electron donation...the sulfonate ester is a better leaving group...or is this too simplistic?
