"Best class" is a matter of balance. What does the party need? What is the experience level of the players? How many players are there? What restrictions does the DM use in terms of playability in the classes or multiclassing? There is so much more to this than just "what's the best class".
I of course have my own priority. But ask questions that argue conventional wisdom.
Clerics are must-haves is conflict dungeons, but a druid would be a better healer if the campaign involves tracking, traps, encumbering terrain, etc.
Wizards are very powerful, and certainly more so than a scorcerer, but what if the DM has the spellbook stolen?
Rangers are not as preferrable as fighters, barbarians, or paladins in a fight, but their high skills, wild empathy, animal companion and divine casting might make them perfect in a small party...
