HMA VPN Vs Private Proxies for Magic Submitter

Hello,

For a while I'm using Magic Submitter with 10 Private proxies and I'm having decent results.Today,I noticed that MS recommends HMA VPN,so I was wondering what would work best?
The thing is,10 private proxies costs me 24$ each month,while the VPN costs me 11.52$ /month.

So,what are your opinions? Do you have a lower or a higher success with the VPN? The speed increased or decreased while creating accounts and submitting content?

Cheers
