What are the pros and cons of remaining Jekyll?

From the text:

To cast in my lot with Jekyll, was to die to those appetites which I had long secretly indulged and had of late begun to pamper. To cast it in with Hyde, was to die to a thousand interests and aspirations, and to become, at a blow and for ever, despised and friendless. The bargain might appear unequal; but there was still another consideration in the scales; for while Jekyll would suffer smartingly in the fires of abstinence, Hyde would be not even conscious of all that he had lost. Strange as my circumstances were, the terms of this debate are as old and commonplace as man; much the same inducements and alarms cast the die for any tempted and trembling sinner; and it fell out with me, as it falls with so vast a majority of my fellows, that I chose the better part and was found wanting in the strength to keep to it.
