Keeping Vita or PS4 for most indie titles. I'll grab the odd Switch physical release - like the Wonderboy remake that's getting a physical Euro release next year. But unless the indie title is one I dearly enjoy I don't feel the need to double dip again on a Switch version, going forward though I may opt for Switch over PS4 as long as performance is identical between both.
Speaking of which, has anyone tried the Slain port for the Switch? I loved it so much I platted the PS4 version, but the Vita version was awfully compromised (barely 30FPS most of the time with horrible freezes every couple of seconds, looked amazing though on the OLED model) so I'd be tempted to get the Switch version to have an actually decent portable version.
