I'm a huge fan of TLAO and have actually bought I think six copies of the book (four were gifts, one was a loaner that because a gift when the borrower liked it so much, and a new loaner to replace the lost one). I use it nearly every time I go out. Several pages have fallen out of the spiral binding and been taped back in. It's covered with dirt and grass stains. The corners are all chewed up looking. Every page has notes for the first time I saw each object with each of my telescopes. It's a well-used and well-loved book. I'm doing my best to rationalize buying a 5th edition now that it's out. The finder charts are geared for a conventional straight-through finder with upside down images and to me are a great tutorial for using star charts later on. When I bought my ETX-90 and a right-angle-mirror-image finder for it I actually scanned every chart in the book and used MS Paint to laboriously flip and invert every map so I could use it with the ETX. Only afterward did I find out the author had a website with different charts you can print out for mirror images or right-side-up images. Ugh. In addition to the maps, it includes text directions explaining what to look for and step-by-step how to get to what you're looking for. After a while you don't need the text directions and can figure out how to get there yourself from the chart but I found it very helpful when starting out.
There are plenty of things to see in addition to the objects in TLAO, so it's hardly meant to be all-inclusive. They were curated because they're either regarded as the best of their type or they're easier to find than others. After you've used the book for a while it's really easy to pick up a star chart and use it to find something else that isn't in the book.
One of the things I like best about TLAO is the nightly moon "tour" guide that walks you through various features visible each night during the moon's cycle. I've gone through each one many times and it never gets old to me. I've tried to find another book with more detail but haven't found anything as easy to use. It's easy to find books with detailed maps of the moon and labels for every crater and feature, it's the "guided tour" aspect that appeals to me, telling me how to find interesting things and then telling me what is interesting about them.
I've tried using Sky Safari but I've really had no luck at all with it. I can't figure out how to make the screen match what I see in my eyepiece so after half a dozen attempts I gave up. Other people seem to find it much more intuitive and can't stand using books like TLAO, so what is best really depends on the individual. Try lots of different things and see what works best for you.
