Buying a VPS is always a better option than buying those game server slots...you get root access and the option to use your vps for many other purposes as well.This is also a cheaper alternative!
If you are just going to host your samp server and want a very cheap alternative, you should check out amazon aws
P.S-They're providing a free tier for 12 months with which you can run a single vps with 1 gb ram and 10-20 gb useable storage(depends on your os) for 12 months for free
