To me, and generally speaking, there is a distinct difference in sound between Accordion reeded instruments (Hybrids) and traditionally reeded instuments. Far more difference, for example, than between a low end and a high end traditional reeded instrument (again IMHO). Which is better is completely a matter of individual taste. I prefer the traditional reed sound, others will prefer the Hybrid sound (And price!).
The only real answer is to try out as many as you can across the whole range.
