I do love that Ahsoka and Luke have gotten to meet, man imagine the stories they will share! I'd be curious in Luke actually offered the role of master at any point and she turned him down. Its an interesting mix, Luke is probably stronger with the force overall but Ahsoka has had years of Jedi training, not to mention years of war as a jedi and general. I would be curious what their dynamic ultimately turns out to be. I also give the show props for continuing to put Luke on the screen, while its clearly CGI and a bit wooden honestly it looks pretty solid, solid enough that I can suspend disbelief.
But what's more interesting is perhaps Ahsoka and R2D2. It has never technically been addressed that R2D2 worked for anakin and would know a lot about him; we have never had the chance to see Luke talk to R2D2 about that. Now in theory R2 would have told him at some point, but if not, I definately think he would know now that Ahsoka has come and seen her old droid friend.
