If you will enjoy playing a slower-pace combat game: scouting ahead for enemies while hidden, hit-n-run type of character, then survivor will suit you well. You will probably use a bow until later in the game when skills and new items give you more choices. You can cast wizard spells at range and opponents wont see you while using the hide skill, which is kinda too easy but the only real power the survivor has.
Otherwise warriors and wizards can do everything a survivor can, and do many things better. Its not a fault of the survivor class, per se, but the open-ended nature of the skill-system. There is little distinction except warriors get the most useful special ability for combat -- which is the focus of the game. Wizards get 20% or more more Mana for spells compared to the other classes.
You can do well with any class in the game, as none are too weak. It's just that none are too different from the others. If you dont like to pause the game much, I suggest warrior for the extra survivability.
