to me they both are great, it only depend on what type of game that you are playing.
if action it would be great on console such as ps vita, nintendo switch or simply a PC/laptop.
e.g.it's like pubg mobile, despite having "mobile" but i am certainly most gamer would enjoy it way better on tencent gaming buddy (an emulator on PC)
On other hand, mobile is only suit for playing turn based strategy, or some game require to be online a lots to catch up event from time to time.
but if i have to pick i would choose mobile game for several reasons:
-i don't have much time as i used to (back to 4-5 years ago my favorite would be handheld game console)
-my old pal ps vita have not got any news game that interesting me since 2016 (expect series utawarerumono)
-maybe the last one would be what i try to hold myself back, i am not addicted to mobile game as much as console game (easy to pick up and easy to leave it)
