Efficiency: Rserve has to convert the data to the Rserve wire
protocol, send it down the loopback network and unconvert it at the
other end, whereas Rpy does conversion in memory when needed and there's
no transport.
Simplicity: Using Rserve means making sure the separate Rserve process
fires up when you need it, whereas Rpy just loads up libR.so (or .dll)
and works like that.
User-friendliness: OpenEV is not the most standard-looking GIS program
on the planet - it was never really designed to be a general purpose
vector and raster GIS anyway, which is what Qgis does well.
That's probably enough reasons!
