Well for downloading files and do all the other things (not possible on Reaction OWB yet) you can switch to NetSurf 2.7 and when needed using it side by side with OWB.
About homebanking and other Javascript issues i think that problem are quite delimited to the WebKit version used in that specific OWB release rathen then real limitation of the browser, for example did you try to switch to version 3.30 or 3.31 and retry your homebanking ?
I know this isn't so good but various OWB release have this kind of "little bug", but mostly it can work
only better than IBrowse in all areas.
OWB support all modern web standard, modern Javascript, modern HTML 4 and 5, CSS 3 while IBrowse is limited to an incomplete Javascript 1.5 support, an incomplete HTML 4.01 standard and no CSS at all
Aniway to turn on topic IMHO there is no reason to use IBrowse on UtilityBase,as there are no file to download, Flash to use (also very limited too) and so on and even that there not worth to use it ...
At the end don't forget that MUI OWB is on the way, they just need the update 3
