Well its all a matter of personal taste. They both have great assets.
The memorizing adds somewhat more difficulty and realism into the gameplay.
You would be required to think (as mages are supposed to be good at that) it all thoroughly before heading into combat.
While a manapool and standby spells give somewhat more faster game action.
What i think would be a good comprimise is to combine these two in such a way that you have to memorize what spell you are going to use and then when the situation comes that you'd be able to use that spell untill your manapool runs low. the number of spells able to memorize will be dependent on character lvl's and class. So that a warrior would be able to memorize say 2 spells on lvl 20 and say an archmage memorize 6 spells at the same lvl.
Hmmmmm but i am getting a little <img src="/ubbthreads/images/graemlins/offtopic.gif" alt="" /> here, what i also think is that sleeping shouldnt heal a character instantly to max hp. Say when you have a broken leg you wont expect it to be healed the very next day now do you? You should heal only a couple of hp. If ya want to heal more hp either go see a healer (gives a good excuse to use these lads efectively) or cast a healing spell. Mana however is a complete different story though since mana is more based on your mental capacity's and the reason you run low is because your mind is getting tired. When a person wakes up the next morning he should be mentaly fresh again (that is if he had a normal nights rest). And foods and drinks? I think you should need that to stay alive. In gameterms: If ya dont eat or drink your body starts deteriorating. In other words you start losing hp slooooooooooowly. See how you like it the way you treat your character in the game. Try to survive for 4 day's and nights in a row without even 1 sandwich or glass o water <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
So maybe an hunger/thirst bar can add more excitement in the game aswell as more realism (skip the peeing and poopin part, lets yust say they do such a thing when they go <img src="/ubbthreads/images/graemlins/sleepey.gif" alt="" /> <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />) Well so far my suggestion <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Hope ya'll like the concept.
