Mine have been pretty consistent through both seasons so far. And I can't really see them changing.
Short answer: AJ and RD.
Why? Because I can relate to both of them pretty well. And I feel like my personality kinda fits between the two of them (almost equally, which makes it hard to pick a favorite between the two). I'm drawn to RD for her loyalty, quickness/agility, and sense of humor (though it can be a bit rough). Oh, and pagasi are best variety of pony (I think I somewhat envy the freedom she has because of her wings). I'm drawn to AJ because she's practical, athletic (though more geared toward strength), and... just some things that really remind me of myself, though I can't really describe it well.
Something else of note: Blue and orange have been my two favorite colors for quite some time as well. So this also draws me to them a bit, aesthetically.
To an extent, you could say I like the ship between these two as well. Though I think of it more as the two of them being lifelong best friends. And that's another thing I somewhat envy with them, because it's that kind of close friendship that I find most fulfilling.
