If you're at a scratchy angle, it is much more difficult to beat a pocket with follow than it is with draw. A ball with draw grabs the cloth immediately, but follow jumps the CB off of the table and needs to wait to land before it grabs the cloth.
Follow may be a small bit easier to execute in long distance cases because the cue elevation is more level than the same case with draw. But if you have a good stroke or good squirt-swerve intuition then it isn't an issue.
When against the rail, if you hit top with spin, the CB will swerve immediately, faster than it squirts. If you learn to compensate for this you can get out of sticky situations with a lot of spin.
You can also use draw when you're against the rail by hitting through the edge of the bumper itself to catch the close edge of the cue ball, but it isn't very easy to execute well.
In general, a ton of players hit both top and draw shots too hard with a punchy stroke and too short a backstroke. Assuming you are using closed bridge, if you take a long backstroke, and then push the cue far through the ball and let the taper of the cue wedge open your bridge hand fingers, this is by far a better and more accurate stroke than punching at the cue ball and letting the cue come to rest by reversing the force using your stroking arm.
Steep angle top is also good for tickies to get to the corner.
That's all I can think of right now. Enjoy!
