For me it depends on how long the Insider programme will continue in the longer term.
The latest blog post says that the Insider programme will continue past 29 July, but doesn't say for how long, and unless there was a commitment that it would go on for ever (or at least 5 years or so), I'd probably move to the 'Current Branch' or whatever it's called before July 2016.
I'd quite like to continue being an Insider but would always want an easy way to get to 10 proper, as I have Windows 8.1 licences for the devices I have and wouldn't want to miss out on the offer to upgrade to a permanent 10 licence.
