I hope this question actually is in order since it does not seem to have a "correct" answer:
I am about to get into drawing game-theoretic trees and while I am familiar with LaTeX in general, I am not so much with TikZ and particularly not with the drawing of trees.
From what I found, tikz-qtree and forest seem to be the two most common packages to be used (please correct me if I am mistaken). Since I will have to use the syntax of one either way, my question is: which one of the two to go for. Is one considered easier to use, more widespread/stable, more flexible, etc. - or are they not actually to be compared?
tikz-qtreeis more widespread,forestmaybe more flexible (but they are both TikZ, so flexibility is not really limited...) – LaRiFaRi Aug 18 '15 at 10:18forestwould be a better choice thantikz-qtree, which was designed primarily for the needs associated to drawing linguistic trees. As @LaRiFaRi notes,forestis considered to be more flexible. This is true mainly because it provides simple ways to access the full flexibility of TiKZ within a tree; intikz-qtreeit's usually a little harder to access. – Alan Munn Aug 18 '15 at 12:57tikz-qtreehaving mostly usedqtreeorforest, but I preferforest's notation toqtree's as I find it easier to relate the notation to the structure of the tree. (Linguists may not find this but possibly becauseqtree's notation is based on a discipline standard? Not sure.) For game-theoretic trees and tree proofs in logic, I thinkforestcan be better, at least if your trees will get complicated. However, I thinkqtree's manual is more accessible if you are starting this from scratch. – cfr Aug 18 '15 at 13:08forest's notation for trees and a few selected features is included in the second part of my answer to an earlier question. That might possibly be of some help in getting started withforestsince the manual is a bit intimidating. Once you have the basic idea, the manual is really rather good, especially combined with examples from this site. – cfr Aug 18 '15 at 13:12tikz-qtreeandforeston a tree of the sort you are asking about. You can see that thetikz-qtreeversion is much clunkier for this sort of tree. In fact, perhaps your question can be closed as a duplicate of this one? – Alan Munn Aug 18 '15 at 16:30forest, the notes there might be helpful to get started. It isn't a good question for help deciding which package to use to draw trees of this sort, and I didn't mean to suggest otherwise. – cfr Aug 18 '15 at 20:26
