Only way is to try it and see for yourself. I used to play competitively using 2H, although it was solid and reliable, I felt it was only mediocre. Switched to a 1H after a long break and found the power, spin, and angles I was looking for, but it was never as solid under pressure as the 2H. Now switching back to the 2H and finding power and spin through improved technique. There are advantages and disadvantages to both, only way to see which one fits better for you is to take the time to learn it and see for yourself.
