For full game runs (any%, any% NG+) EMU offers considerable advantage due to load times vs original hardware PS2, so comparing the runs isn't really possible in my mind. My personal preference would be toward promoting original hardware but don't want to put any barriers to entry up to new runners. I think we can all agree the more runners the better.
EMU might fit better on xbox boards? I haven't tested but my hypothesis would be the load times are comparable. Or maybe add a standard amount of time to compensate for loading advantage on ps2? Not sure what the best way to approach this or if the current way even needs to be changed but I've been thinking about this for a while now and wanted to pose it to the community.
Would love to hear your thoughts.
