I'm liking Dreamfall Chapters, I think it's excellent.. the opening of the first episode basically answers one of the big ambivalent questions from the last game, which left some with a bit of feels.
Life is Strange is.. eeeeeeeck, it reeks a bit of the angsty teenage drama ala Gone Home but I like to think it's better than that, which it might be.
Temptation to buy rising. XD At least if big question being answered is what I think it is.
Were Dreamfall and the Longest Journey two different games? I just know I thought the Longest Journey was an interesting paralell to Life is Strange while playing Life is Strange, I ended up enjoying Life is Strange a lot more though, honestly I couldn't even get that far in Longest Journey. All the criticisms people leveled at Life is Strange based on it being a failed attempt to connect with people or artsy and all that applied way more to Longest Journey than Life is Strange IMO.
I loved TLJ. Of course, I also played TLJ two or so years after its release date. If memory serves, between Infinity Engine games. Back then, it shone brightly as this awesome little story with some lovable quirky characters. By modern standards? TLJ is a bit closer to old school adventure games than what we see today which may make going through it a little frustrating to some. Some of what it did has also been done better by other games since then. Back then TLJ was novel.
I think taken as a whole, TLJ and Dreamfall told stories worth experiencing. Unfortunately it's kind of like the old Fallout games in that I find it hard to recommend playing them to people who missed out before. TLJ just hasn't aged well. And since you disliked it to begin with, eh... yeah, maybe read a wiki or something and start at Dreamfall instead.
You don't really need to know April Ryan's story to get into it--although it does provide context for her characterization in that game.
No idea if Dreamfall Chapters is a good place for newcomers to jump into the story.
