Serverguard or ULX

ULX is the OG man, its probably the most friendliest and easiest

Serverguard is a genial very expensive addons but it is perfect ulx is too basic

Serverguard is better optimized it has big lib and Web statistic.

ulx because on it all Addons are adjusted, many got used to it. The choice is obvious

Most of addons has ulx support, i think serverguard is slowly dying

ULX has so many features that I think it's the worst.

ULX is probably better but has the worst interface that I just can't help but use ServerGuard

I prefer ULX because it looks more modern and in my opinion feels snappier than serverguard, it is also free.

ULX is free, simple and compatible with almost everything,
Serverguard : Its more sandbox / Darkrp, more customizable,

i prefer ULX due to familiarity and im able to utilize it very well
