A2 and SG are comparable, more or less. Generally, SG a little stronger but then has annoying CPU usage restrictions (they complain when you use too much). A2 got better pricing and performance isn’t bad either. SG is probably better in customer service.
For those that care, SiteGround FEELS like the better webhosting service.
- Website and overall UI looks better.
- Price is higher.
- Service seems faster.
- Customer support seems friendlier/better.
A2 isn’t completely inferior:
- It has lower pricing.
- It seems to let you have more visitors.
It also seems that people who leave SG, do so for pricing reasons or they’re upgrading to VPS. People who leave A2 seem to be angry at performance or customer support.
