I personally like Virtualizor but it's not as well known as Solus VM. Solus VM can create VPS Resellers too. Which one do you like the best and do you like it's interface? Thank you.
Dedicated Servers WHMCScontrol panel
Other two? I believe, the "rlshosting" user has provided only two options i.e. Virtualizor & SolusVM. Since, solusvm is integrated in the WHMCS and widely used, I believe it is best.
Prefrence goes to SolusVM but that does not mean that the other two are not good :)
SolusVM is best when u can easily make vps reseller from them
SolusVM- It has tight integration with WHMCS.
