Most competitive golfers have a go-to shot shape - draw or fade - they use for most of their full shots.
You get into trouble, however, if you're a draw guy like Rocco Mediate who simply cannot/will not hit a fade on any occasion. Recall Mediate's 2008 U.S. Open playoff loss at Torrey Pines to Tiger Woods. Tied after 18 holes, the pair went to sudden death on No. 7, a dogleg right par 4. Mediate drew his drive into the left fairway bunker, and ended up with a bogie, losing the playoff.
Like you Jakester, Jack Nicklaus was big on the fade; but, he eventually learned to hit a draw when he needed to. (See Jack's book, Golf My Way, for details.)
I talked to one mini-tour player: He draws his 3W and 5W, and fades most other shots.
Many golfers learn to "go the other way" on tee shots, where you have ideal conditions: You're standing on level ground with the ball on a wooden (or plastic) tee.
Years ago when I could play three times a week, I would fade or draw as needed. On good days great... on bad days, really baaaad!
Wow! Good memory, I had forgotten about the sudden death play off after the 18 hole play off.
To the OP, I can hit both but notice I score better with a fade. After trying really hard to hit a draw, I developed a hook as my miss. I went back and had to start hitting a fade again, to get rid of it...lol
