Modern games should have:

- Quickplay

- Server / Game / Match finder

- LFG - for a more detailed search

Each of these has a different use case, and a single user may make use of all of them (I include myself here). Not everyone wants to just click "play", it's very dependent on the type of game.

Helldivers 2, for example, implements the first two. Destiny/Destiny 2 has mostly the first one. Destiny on Xbox has a XBL-provided LFG functionality (but prior to that external sites were used). You really needed LFG for finding a raid group.
