AlphaVPS verzus Kamatera 2020

migration from Contabo to my own physical server that will be port-forwarded to public network using OpenVPN, so the main task of the VPS is to route traffic to different Virtual Machines on my physical server with the highest performance.
I really like the fact, that they give 4 options of CPU rental. Most important are two options:
A: Availability - using VPS with A-Type vCPU I noticed slow performance, because of low VM Priority, so there was resource expropriation occuring.
B: General - you rent whole core of the CPU, so you can use 100% of your CPU Core. The performance difference between A and B is huge.
The difference in price is directly proportional to performance difference.
Network - I chose an option 10gbit/sec with traffic limit 5TB/month. I am not sure if this is up to 10Gbit or dedicated 10Gbit, but I guess this is "up to", because it is a bit slower...
During this review I performed a speedtest. Results (Frankfurt):
Ping: 1,373ms
DL: 2.5Gbit/sec
UL: 4.2Gbit/sec
I think these results are very good, network capacity for physical server is 1gbit.
Support is great! I had some issues, they are very helpful, every client has their personal contact person - this is amazing!
I really recommend this company.
-1 star in features for lack of System Reinstallation Option. I failed with network configuration and lost access to server. I created a ticket to support to re-install software and I was told I have to remove VPS and then create the new one. I do not know how this kind of actions is being billed, because I was in the trial period. Also, I wanted to add 2nd SSD Disk for backup storage - I am unable to do it. I can only expand it, but I need another disk/partition... So - once again - seems I should remove VPS and create new one. But I will not do it... Pity
Currently there is a subdomain vpn-prod.stelmaszyk.dev, but it's gonna be changed once migration via pre-configured VPN will be completed.

nstalled everything the same on it and sure enough after a while of us announcing we have a new host we got DDoSed, not only did the service not go down but I got an automatic email notification.
2. False 1gb port, this new host also claimed to have a 1gb port, not only did if have super fast files transfer (unlike you guys) when connecting to Minecraft servers it was able to ping the numeric IP instantly unlike you guys where it took several seconds to ping
3. Expensive pricing, when I first found you I thought you where the cheapest but this company that I moved to DONT have shared cores and have 10 cores dedicated to me with 50gb ram and 1tb SSD, they have better specs than you as well,
4. When my VPS got compromised and BW filled up you charged me 10 EUR for an extra 1tb of BW, which is the same price as the actual VPS, it's not as if you gave me 16gb of ram and 160gb SSD you just gave me bandwidth
Yes I did a previous review and that was the day after I purchased it
