sultan i using aapanel from 2020
and the only issue is "aapanel crash/some feature bugged"
that's only the main issue, (i haven't see this again on 2021)
if aapanel is worse cpanel ever, hmmm maybe it's depend on your sites, the inside of the sites, and the visitor....
i using AAPanel with OpenLiteSpeed and anything working fine, maybe if you using apache, you can change too into OLS, and do some ip throttle to make the server faster.....
i think until now.... there's no big issue,
if you using wordpress... then you maybe can check the spec of vps...
if you running on 1GB Ram and 1CPU, this will hard to you....
if i can suggest you. maybe you can use flynet from russia,
since the server is on cold part of russia, they have cheapest price and quite good spec...
you can get good server with only 7dollar
(some of their hardware is old, so ask them first before buying, so you didn't disappointed )
