Well, most of the amazing IIDX players out there play on 2p side because they started playing when the original 5-key, beatmania came out. As it was ONLY right handed disc.
There are plenty of players out there who can get equal scores with the 1p side, however there are a larger majority seen playing 2p side.
I'm right handed, and I play 1p side. - You could always switch it up, as its a good idea to become versatile with your playing style that way. - but in no way is it necessary and or better.
Its all just what feels best to you, and what you learned on. |
