Specs
Pros
Pro Easy to control what players can see
With any subscription ($5/month) on the part of the GM, Dynamic Lighting can be enabled. This allows players to only be able to see what their characters should see, without any management by the GM. Light boundaries must be set up beforehand, or you can buy professional maps.
You can use fog of war for free, which has simple controls.
Pro Very easy to create 5e character sheets
Charactermancer uses SRD content, and any purchased modules to turn character creation into a multiple choice wizard. No need to type in the text of spells or abilities, the weights of objects, or calculate your armor class. This is all performed automatically.

Flagged Pros + Cons
Con Doesn't integrate with D&D Beyond
If you and your group make heavy use of D&D Beyond for character sheets, you will find there is no import feature or any kind of linkage. You have to rebuy content and rebuild characters.
Con Was useless if you don't play D&D
If you're looking to play anything other than D&D you have to shell out a fair chunk of money to have the rules.
