Ask HN: VPS Linode Vs Digital Ocean

I'm trying to decide between these two companies: Linode vs Digital Ocean for a new VPS.

My needs are: potentially heavy CPU, and heavy memory usage.

I'm using a Amazon EC2 (Micro) instance right now - and paying ~$25/month for it (its never shut down) - which seems pretty non-cost effective for a VPS from Amazon that never is shutdown.

One of my biggest gripes right now about Amazon is its slowness (via Micro instance which makes sense having only like a .5gb of raw) where i could get a lot more hardware for potentially the same amount at Linode or DO.

Does anyone have statistics on the number of nodes (e.g. other client accounts) running on the same VPS for linode or DO?

I'll be running Ubuntu, with python stack

Thanks
