Seeking advice on driver tube for SE 300B

Dear cheaplow and accphoto
Here are three schematics for 300B single ended amplifier, do you think which is the best schematic. I am seeking your advice before I buy the parts. I am looking forward to receiving your advice. Thank you.

I decided to try the first schematic first. Thank you for your recommendation.
