Comapring these two web hosts I'd focus on the points:
HostV.com - very beneficial pricing, but since this is a one-time offer you will have to pay annually to get 50% off the deal. Think whether you like it or not.
Serverpoint.com offer VPS on the servers with RAID 10 and hosted in their own dc.
I also think you shouldn't limit your choice by these two companies only.
