Of those five I would look at the Axe and the Drone.
The Axe is a great inexpensive inline poppet. It shoots amazing and for most has comfy ergonomics. The maintenance and learning curve on the Axe is a little higher than on the Drone. Personally I'd toss on the clone grips on the Drone and have a huge smile on my face after the 10k break-in period.
Just another genius, billionaire, playboy, philanthropist!
