Kinda? It's a hard question to answer because here's the funny thing - if you asked anyone, it would seem like Siege is my favorite. She's treated like the favorite, goes more places with me, does more with me, and is on top of me all the time (literally). But my connection with Trent is deeper, we have a better understanding, and he's a lot more in tune to me. He recognizes all my cues and anticipates what I'll ask of him, and everything he does, he does with intention and deliberation. I think a big part of that is how hard and long we worked to build this relationship.
That said, I enjoy Siege more. For me, she is more fun, she is easier because of her drive and dependence, and she is intensely affectionate. She gets to go more places because she is more social than Trent and takes less management, not to mention more portable. She's also more reliable off leash (by a considerable amount).
Trent is like my partner in work and life, but Siege is like my feral little baby, working for me (and for herself) rather than with me. The bond I have with her is more loving, happy, fun, and sweet. The bond I have with Trent is based on a mutual respect we're still continuing to build and an understanding. Essentially... Siege needs me more than I need her, but I need Trent more than he needs me.
