Pros
Pro Free basic rules PDFs
Wizards of the Coast provides free PDFs containing the complete core mechanical rules of 5th Edition D&D (combat, exploration, spellcasting, etc.) and a selection of iconic character options, monsters, magic items, etc. drawn from the full game. Though short on variety, the basic rules are almost playable and accurate to the full game.
Of course far more is free in older editions as well as cheaper, 5e is by far the most expensive edition, and it is almost as bad as 4th edition.
Pro Bounded accuracy
Bounded Accuracy is a core design ideal of 5th Edition. In short, it means the numbers don't get too big; this lets weak challenges remain relevant for longer, and strong ones become survivable sooner. In practice, it also places more focus on a character's inherent stats and less their class or on magical equipment than has been the case in recent editions, which is a another major downside to 5e.
Pro A good mix of the best rules of the previous D&D editions without the worst things
Cons
Con Almost no published material for 5e
WoTC has been super lazy since 3,5 and even that had only a third of the material available that TSR published for AD&D 2e.
Is is sad that WoTC after 7 years has not supported 5e or other versions better.
This is a great reason to look into 2e or 3,5e systems instead of 5e.
