Frankly, I couldn't work effectively without either program. The weaknesses in one program are balanced by the strengths in the other, and each does things the other won't do. PSP used to be considered a hobbyists program, but it has grown since then and is now considered a fully professional level program. Photoshop is the standard, and if you ever do print work, the printer will often ask for psd files so the rgb layers can be seperated. Both programs are simply indispensable if you want to do graphics professionally. And darn near indispensable just for hobby work. The ability to composite and work with layers in photoshop can't be beat. And PSPs text handling capabilities are unsurpassed. Not to mention that the same plugins will work in both.

Talent is God's gift to you. Using it is your gift to God.
