Which one will you prefer? a paid host or a free host ??
I will prefer a paid host indeed. They are much reliable though not much affordable.
A host which is reliable and affordable are difficult to findd these days.
If your looking for quality hosting with good uptime, then its best to go with paid hosting. Even with paid hosting, you have to ensure that you do not go for the cheapest, as you should know by now that cheap doesn't mean reliable.
