The statement to draw the maximum you can adequately handle is not really a flippant response, but it does imply the need for care, training, and much practice. But regarding the poundage selections that I see most commonly on this site, it seems that most of the guys seem to be from about 45# to 55#, give or take a few pounds. You do see a fair number of guys listing 60+ pound draw weights described, especially for the larger animals.
If you are most comfortable on the lower end of the scale, there is no need to feel under equipped. As others have stated, arrow selection, tuning, and tactics play a major role in your effectiveness. So draw weight is not the entire picture.
My preference is my 65# Hill bow, but I had an injury a couple of years ago, so my 55# Cheetah has become my go to bow. On it, I shoot cedar arrows with 125 grain Zwicky points.
After all this talk, shoot what you prefer and with what you are most proficient.
