so is it better to bend the tip than to cut off the tip?
There's no better, just opinions and style. You have to find out what works for you. Even if your set-up was similar to mine, and your soil was similar to mine, and your nutrients were similar to mine, watering methods, temps, lights, fans, ducting...etc.....your plant would still grow a little differently than any of ours.
Cutting the tip off is a fine way to go. I used to top once, and then top 4 times 2 weeks later, then veg for two weeks and flip and I'd have about 8 colas and some lower branches for hash and tincture. I had good results.
Now I FIM at about 8 inches instead of cutting the whole tip, and then lollipop and either super crop or bend some tips back and forth. There is also another method that is I believe called breaking the "inner hurd" which I don't have any experience with yet.
