In past tournaments, the PSN and mobile each had their own unique tournanments. In the ST:TNG and TZ single table tournaments, the PSN scores were significantly higher. If I remember correctly, the PSN top 4 were higher than number 1 on the mobile devices and some participants played both tourneys with lower scores on mobile. So this is very true that consoles seem to be easier to put up higher scores.
Having just got a PS4 and TPA, I can vouch that the PS4 version is so much easier to play.
