On a Smartphone! Nah.. i'm just kidding you. What a question man! How can ever anyone play better on small smartphone's screen with just restricted options and needed to tap with a big finger super small buttons?! I don't think you asking this seriously, do you? However, there are times, when i do that. For example, if i'm not at home, but don't want to miss some big Freeroll or such stuff. And then it's more like a Torture, than a good game.
I play very rarly at smartphone only when im traveling or somethink, the reason is very easy at deteskop u can handle many tables easier and faster then at phone.Deteskop u got evrythink more advenced at options etc. and i realised thath many tournaments i tryed to find at phone not showing up.
i like Computer for online poker ,smart phones and tablets are ok but are for more of a killing time type of thing like maybe zoom fast cash tables or something like that
I prefer the computer because I like the bigger screen and it seems to have more options and is easier to navigate around. Also there are poker sites that you can't even get on a mobile App. All around it's just easier with a mouse and keyboard.
Obviously the computer has an advantage, I don't open it, I use as much from a smartphone as I do a mobile phone wherever you go and play, where distractions have shifted.
I certainly play better on the computer, which in turn is much more comfortable and dynamic, where I can see and choose my tournaments better and open more screens, but I also use smarthphone to play some pppoker tournaments, I never play with the two or one or the other and for me computer.
I play better on computer but I play on my phone all the time I can play anywhere that's pretty awesome cant be at that but you got to consontrat when you play on your phone cause you can get distracted real fast
