Since you have some info about game, what paths do you like, and what mythic paths you feel are weak?
I enjoyed playing Demon the most and consider it to be the path with the most flavor, but if you do not rest frequently then its 1 of the weaker paths, because its strengths are all tied to Demonic Rage which is an ability you can use twice per rest. If you ignore the Narrative components then the most consistently strong are Angel and Lich. They are the only mythic paths with a spellbook that ramps up to level 9 spells and the spells inside of their spellbook are exceptionally impactful. If you play them on a full caster and merge spellbooks then they are flat out broken because of how many levels their spellbooks are ahead of the actual content. Azata and Trickster are then both fairly powerful, but for different types of builds. Azata synergizes well with Kineticist, or with casters. Azata casters are not as poweful as a merged spellbook caster on Angel or Lich, but they are the next best thing. Trickster synergizes well with any martial character. With the improved critical line of feats, you can have a crit range of 11-20, 1. Then there is Demon and Aeon, who, out of the early game paths, are in my opinion the weakest. Both of them have some synergies with some builds (demon with kineticist, for example), but for the most part don't really work well with anything. Aeon does have some nice toys later down the line, in particular, its spellbook is in my opinion superior to demons, with spells like edict of predetermination or edict of invulnerability, which are cast as swift actions and have extraordinarily powerful effects (fixing dice rolls to a specific value and making you immune to almost everything respectively), but its even less synergistic with specific classes than demon is. In theory it should be good with minions, but summoners really do not scale well on higher difficulties and the class suffers as a consequence. When it comes to the late game paths, all of them are very rushed and suffer because of this. Out of them legend is the strongest, by virtue of giving you 20 additional levels to play around with, but legend doesn't feel particularly interesting to build.
In terms of their flavor, I found Angel to be the least compelling and I am not sure why people consider it to be 1 of the paths with the most content, when for the most part you end up just going to zones other paths also go to and talking to NPCs available to everyone else. The content available to Angel is the most path agnostic, most of it you will get a hint of when playing other paths. The reverse is not true for other paths. Every path gets to interact with the Hand of the Inheritor or Targona, but Angel is not able to interact with, for example, the Azata's Court. Nothing about Angel stood out as being interesting or inventive to me, it was just a generic good path that gave you what it said on the tin. Aeon on the other hand, was the path I felt the most conflicted about. The time travel segments are interesting, however whenever you were called on to deliver justice I felt like 90% of the dialogue options were written by a mob on twitter, because the conception of justice was about on that level. There was a very clear narrative inconsistency there which just made the whole path feel a bit off. Lich is a generic power fantasy. If you enjoy that kind of story, then it will probably hold your interest. Azata is a different flavor of good to Angel, with a more "screw the rules" approach to solving problems. It has more content than Angel, with the MC receiving an intelligent animal companion which will comment on many of the events which occur within the game. Trickster is the prankster mythic path. I personally do not appreciate the trickster brand of humor, so for me that put me off, but I suppose if this is your style of humor then the path is great. Demon is the evil mythic path played more or less straight. The choices you can make there are mostly motivated by self interest and as expected of an evil path are often not particularly logical, but there is so much reactivity to the demon mythic path in chapter 4 that it makes the path feel much better to play as a consequence. Legend, Swarm, Gold Dragon and Devil only appear in Chapter 5 and so there is not much content allocated to them to comment on. Even then, I didn't play much of any of them although I did try them all for a bit, so I can't really provide much commentary there.
