In general, I would recommend choosing a VINTAGE table that is
1. available
2. in excellent condition
3. is easy to maintain.
I do not know the Q5, but it appears to be a linear tracker so it might be more finicky and harder to find parts for.
I would recommend choosing a NEW (or "non-vintage") table that is
1. in excellent condition
2. has only one agenda: to play records (simply put, no USB input, no preamp built in)
I would tend to avoid the ION and Gemini tables, I think a well-serviced vintage table will give you more spinning time.
I have no experience with either table you mention, but threads that pit one particular model vs. another particular model are hard to answer. On vinylengine dot com they must list at least 100 different Technics models!
