I prefer to play on PC as I tend to do some other things alongside usually as I play MTT and when/if I get later into tournament I feel that my concentration is better while sitting instead of chilling and laying back on the couch.
I like to play on my phone because it allows me to play when I'm not at home, but I feel more comfortable playing on my PC because it allows me to play more tables at the same time
I think the best way is a computer to play poker if you play a lot of tables at the same time so it's best for me to play from my phone too, but you can't play a lot of tables there
I prefer to play on the PC, you can play in more than 1 room, .. But to play at 1 table, I think it's more practical on phone, but some Apps don't have the same features as the PC software..
Pc is so much better to me. I feel I need be propely sitted to play relaxed and confortable. I get to play better this way, when I'm more focused I think.
But playing at the phone can be convenient sometimes, no doubt about that.
