There isn't option that would suite me. For multiplatform games I always choose pc and steam. Platform exclusive choice is similar as the choice between android/ios. Difficult to pinpoint to exactly 1 reason why I would upgrade console to one brand or another. I guess my choice would be eocsystem based where ecosystem consists of quality, performance, exclusive content and features, friends, existing purchases,...
I bought ps4 for gran turismo, uncharted, dreams, horizon dawn zero,... all those sony specific games that don't really exist in form I prefer in other platforms. PSVR was a nice surprise and that might cause me to upgrade to neo.
