New Blogger or Old Blogger?

I use Old Blogger to maintain this blog. Google wants me to press the button and switch to New Blogger. I might as well do it, Google contends. More reliable, new post labels, better template editing, and privacy controls.
And then the kicker -- within a few months, they will force me to switch, anyway.
Two clients of mine are using New Blogger: and all is well. However, they have brand new blogs with few posts. I have over 300 posts in this blog.
I tested New Blogger in Beta in November -- boy was it buggy! I'd hate to push that "switch" button and have it all go haywire: because apparently, there is no going back once you switch.
So: what should I do?
Go ahead and push that button? Or wait until I am forced? Or something else?
