I'd also say wait for RTM. From what I gather that could be closer to the end of December, precisely because MS still has to deal with all the issues potentially caused by upgrading without a hard reset. Those issues are irrelevant for the first W10 devices coming out, because for them there is no update process from WP8.1 to worry about.
In general, anything that isn't RTM could potentially require a hard reset for it to work well. I'm sure you already knew that, but were just hoping to get different advice ;-)
