I wouldn't put an Assegai down on the list for tyres that work great in the dry, but it is fully capable. And without knowing what Schwalbe you are considering, hard to advise.
All the known brands produce excellent tyres across all spectrums of riding, it really comes down to your own preferences. Most of the tyres share the same rough design, mostly to get around patent infringement, and unless you are looking at full wet or spikes, they could be said to all be much of a muchness - but some will certainly not be suitable for specific conditions.
Depending on the inner width of your rims, you may have a choice to make between 2.35", 2.4", 2.5" or 2.6" wide tyres, depending on the brand. And you might decide to run wider tyres on a hardtail than you would on a full-suspension bike.
Depending on your riding style, you may want to go for a more trail-oriented tyre, or something more enduro-rated or even downhill-rated. The different in the casing will give you a very different experience on the bike.
Then you have your compound, do you want something fast-rolling but that might lack grip? Something really tacky, but that rolls slower? Or something in-between?
