seems both do A/B split testing...which one's better? Anyone has got 1st-hand experience?
i would use http://www.conversion202.com instead. they don't offer lp templates but it works seamless with prosper202 and you can easily track conersion rates etc..i've made the experinece that visual website optimizer etc.loose a lot of conversion therefore you data won't be exact..not sure if unbounce is any better
unbounce hands down... but you do need a heatmap script like clicktale/etc..
another combo worth checking is unbounce + VWO http://unbounce.com/partners/visual-website-optimizer/
VWO is lovely, imo.
