I remember reading on here once, someone saying that Efren can use low spin like top spin. Tonight practicing I noticed that when shooting low on the cue ball, I was quite a bit more accurate than using top spin. Is it just me or is there really a difference with accuracy between the two. I know low spin will eventually turn into follow, but is there any videos out there showing hitting low for follow.
There's a lot that can be discussed in regards to low vs high (your title). But your post talks specifically to 'shooting low for follow', and in particular posting a video as an example.
The technique of shooting low with the intent to allow it to turn into follow is typically called a 'drag shot'. The best video example that comes to mind is the hill-hill between Reyes and Rempe in this clip at about 1:30.

When you look at the overhead the angle doesn't look quite as severe, but looking from the shooter's point of view it looks very, very difficult to pocket the one ball and hold shape for the two. If you slow rolled this ball with top spin it would be a length of the table bunt shot, making the shot more difficult for several reasons. One, it is hard to use a super slow bunt stroke with the same accuracy as a more normal speed of cuing. Another is some people do find it more difficult to aim hitting center to above center. But more importantly it would leave you vulnerable to any trace of table roll or drift.
As played he is able to cue with medium speed using draw. The draw wearing off and turning into natural roll kills a lot of speed, so by the time he strikes the one ball it has the same result as a long bunt shot, yet with much more accuracy.
Generally this drag draw shot is best used when you need to lag a ball in but have a lot of distance to contend with. If you are within a couple of feet you can just go ahead and roll the ball. If you are shooting with the intent to follow the ball more than a little then it is ok to just use a normal stroke with an above center hit. But the kill shot is a good one to have in your bag of tricks for times like these.
Does that answer your question?
PS- I just rewatched the entire video, can't help myself. The 5 ball shot is actually an example of using draw to kill cue ball speed AFTER contacting the object ball. Killing cue ball speed with draw both before and after contact are discussed in Robert Byrne's Standard Book of Pool and Billiards. I consider this the bible of our sport and it is the textbook I used to learn to play when I was a teenager. I would recommend getting a copy. Pretty cool to see both shots come up in one rack, in a key spot, and executed to perfection!
PPS- That 7 ball wasn't in the book!!!
(OK, I supposed you could say it fell under the part about 'burn this diagram into your mind' in which he explains how the cue ball slides along the right angle line for a moment before the top/draw takes allowing you to make some cool shots. Efren hit the 7 super hard to delay the forward motion and avoid a scratch. Amazing shot. But you know what I mean when I say that wasn't in the book!)
