When comparing Monsters & Magic vs Basic Dungeons & Dragons 5th Edition, the Slant community recommends Monsters & Magic for most people. In the question“What are the best tabletop RPGs?” Monsters & Magic is ranked 42nd while Basic Dungeons & Dragons 5th Edition is ranked 47th. The most important reason people chose Monsters & Magic is:
The game uses a single core mechanic, which is flexible enough to cover a wide variety of situations. This helps GMs immensely when characters want to do things that aren't already covered in the system. The mechanic itself works thusly: all rolls are 3d6 + modifiers *minus* difficulty. The result is how many effect points the player can apply to the action -- or, if negative, how many consequence points their opponent can apply to a reaction. Dealing damage is one use of effect points, but there's a limit on how much can be dealt at once, so additional effects (e.g. distracting, disarming, unmounting, etc.) see constant play instead of only being used rarely or by super-specialists. This also means failure is interesting, since it results in consequences! This mechanic is used to do everything, and the game essentially consists of nothing but examples of how to use it.

Pro Interesting combat
Attacks generate effect points, which you spend to do things to your opponent. However, the amount of damage you can do is limited, which forces players to do other things... and the effect system is broad enough that these can be things like cutting off a carrion crawler's tentacles, knocking an opponent's sword out of their hand, and so on. Failures on attack generate consequence points as well, which your opponent can use to do things to you.
Pro Mental defense and hit points
Characters have a "Mental Defense" score and "Mental Hit Points". These are used to help provide a unified system for handling social encounters and mental attacks via magic.
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 abilities and less on magical equipment than has been the case in recent editions.
Pro Easiest tabletop RPG to find someone to play with
As D&D is the largest tabletop RPG franchise and played by most people, it is the easiest tabletop RPG to find players for.
Pro Encourages character immersion
Numerous core aspects of 5th Edition exist solely to encourage thinking in-character, including mechanical rewards for good roleplay and detailed character backgrounds with lasting effects in the game.
Pro Minimal but versatile rules
5th Edition strikes an impressive balance in keeping the rules simple without limiting the creativity of players.
Cons
Con Not currently available in print
Is only available in PDF.
Con Few monsters & spells provided
The included rules have only about 20 monsters and 1st and 2nd-level spells. Third party publishers have supplements that provide more, or you can use ones from old D&D.
Con Lacks variety in various areas
In order to make the character creation fast and relatively simple in-depth customization options have been excluded from the basic ruleset. There's also a limited selection of character options (just 4 classes with a single sub-class), monsters, magic items, etc. The variety is to be found in the full game.
Con Still puts too much emphasis on spellcasters
The sword and sandal brigade, as well as the ever undervalued and undersupported Ranger class (Arcane Archer is under Fighter, not Ranger, where it belongs!), are still second fiddle to the magic slingers and rogues who are always overpowered.
Con Too easy to fall into the meatgrinder trap
Roleplaying falls by the wayside too easily as the murder-hobo set are catered to! Of course, it's also about the DM, however, majority of players want combat and that is exactly what D&D likes to provide - along with the archetypal and archetypical meat-grinder dungeon fest.
