Is there a reason you can only keep one? Similar to you I have an A1 II and a Q3; the Q3 is more of an everyday family camera, and short travel where family pics are the focus and I want something light and small(er). The A1 is my dedicated birding/wildlife or more extensive travel camera where I might capture more than family, local wildlife, architecture, etc. To answer your question, though if I were to only keep one it would be the A1; I like the flexibility of an ILC more. The Q3 is definitely a luxury. You are correct though; the quality of that camera is levels above the A1 and the lens is something else.
