I usually play poker on my PC. I like to play on the big screen, which can easily accommodate 4 or 6 tables.
I think often the typical entry point for most players is via the computer but ultimately it's a matter of type and getting used to it.
Since I personally only played on smartphones from the beginning it was ultimately much more unmanageable for me personally on the desktop since the modern mobile
Apps, especially GG Poker (best gameplay in my opinion) and
pokerstars are now so user-friendly and well constructed that it no longer has to be a disadvantage to be able to play "only" on the mobile.
On the contrary, I think it brings certain advantages.You can play on the road, outside on the terrace with a glass of wine or on the toilet

you are then also not dependent on the breaks and can transfer the session if necessary easily from PC to smartphone.
For more proffesional players who use the appropriate software tools etc. or for streamers, playing on the computer is of course indispensable - multi-tabling is probably also more practical on a large display.
