Help me choose - Linode 512 Tokyo or Serveraxis 512 SSD ?

Hi, I want to try BOA and after take a small research I found 2 XEN VPS that suite my budget and both are reliable:

1. Linode 512 $20 (512 RAM, 20Gb HDD, 200Gb Bandwidth)
2. Serveraxis 512 $14 (512 RAM, 16Gb SSD, 500 Gb Bandwidth) CPU Spec 3/3 (??) IOPS 1k

Linode Pros:
- Linode has TOKYO DATACENTER which has very good latency ~120ms from my location and my target audience (same country).

Linode Cons:
- Not SSD

ServerAxis Pros:
- SSD drive (speedy for a database intensive app like Drupal, but Im not really sure how fast).

ServerAxis Cons:
- Their datacenter located in Chicago which has not so good latency ~280ms from my location and my target audience (same country).

If Price and Reputation are not important factors,
Which one should I choose between them if performance is my priority ? OR..
In Performance matter for Drupal-BOA performance (speed), which is the better option - Linode with latency 120ms or ServerAxis SSD's VPS with 280ms latency ???

Thank you.
